Chapter 2: Workspace

Workspace basics

Workspace overview

Adobe Acrobat XI opens in two different ways: as a stand-alone application, and in a web browser. The associated work
areas differ in small but important ways.

The menu bar and two toolbars are visible at the top of the work area. The work area for the stand-alone application
includes a document pane, a navigation pane, and a group of task panes on the right side. The document pane displays
Adobe® PDFs. The navigation pane on the left side helps you browse through the PDF and perform other options on
PDF files. Toolbars near the top of the window provide other controls that you can use to work with PDFs.

9

When you open a PDF inside a web browser, the toolbars, navigation pane, and task panes are not available. You can
display those items by clicking the Acrobat icon
window.

Note: Some, but not all, PDFs appear with a document message bar. PDF Portfolios appear with a specialized work area.

Welcome Screen

The Welcome Screen is a window in the document pane that appears when no document is open. You can quickly
access the recently opened files, open a file, and launch some commonly used workflows with a single click.

Last updated 1/14/2015

Workspace

Note: In Mac OS, you can turn off the Welcome Screen by setting a preference. Choose Acrobat/Reader > Preferences. In
the Categories on the left, click General. In the Application Startup section, deselect Show Welcome Screen. There is no
similar option in Windows.

11

Menus and context menus

Ordinarily, it’s a good idea to keep the Acrobat menus visible so that they are available as you work. It is possible to hide
them, using the View > Show/Hide > Menu Bar command. However, the only way to display and use them again is by
pressing F9 (Windows) or Shift+Command+M (Mac OS).

Unlike the menus that appear at the top of your screen, context-sensitive menus display commands related to the active
tool or selection. You can use context menus as a quick way to choose commonly used commands. For example, when
you right-click the toolbar area, that context menu displays the same commands as the View > Show/Hide > Toolbar
Items menu.

1 Position the pointer over the document, object, or panel.

2 Click the right mouse button.

Note: (Mac OS) If you don’t have a two-button mouse, you can display a context menu by pressing the Control key as you
click with the mouse.

To ol b ar s

The default toolbars—Quick Tools and Common Tools—contain commonly used tools and commands for working
with PDFs. Most available tools are included in the Tools pane at the right side of the window. You can add tools to the
toolbars for easy access.

The toolbars also include the Create button . Click the arrow to the right of the Create button to display a menu of
commands related to creating PDFs.

Hide and show toolbars

When your work does not involve using the tools in a toolbar, you can close the toolbar to tidy up the work area. If
several PDFs are open, you can customize the toolbars for each PDF independently. The different customized states
persist as you switch between PDFs.

❖ Do one of the following:

• Select a tool in a toolbar.

• Choose View > Show/Hide > Toolbar Items > [toolbar name] > [tool].

Switch temporarily to the Zoom In or Hand tool

You can use these tools temporarily, without deselecting the current tool.

13

• To select the Hand tool temporarily, hold down the spacebar.

• To select the Zoom In tool temporarily, hold down Ctrl+spacebar.

When you release the keys, Acrobat reverts to the previously active tool.

Task panes

Most commands are now organized into the Tools, Sign, and Comment task panes on the right side of the application
window. Most tools are now located in these task panes. Click Tools, Sign, or Comment to display the respective task
panels.

You can customize which panels appear in the Tools and Comment panes.

❖ Do any of the following:

• To toggle a panel’s visibility, click the Show Or Hide Panels icon in the upper-right corner of the task pane,

and click a panel. A check mark indicates that the panel is visible.

• To open a panel and add it to the Tools pane, choose View > Tools and select a panel.

• To show each of the documents in its own window, from the options menu , choose Show Documents Tiled

or Show Documents Side By Side. To synchronize the relevant pages while showing the documents in their own
windows, from the options menu, choose Synchronize Pages.

• Click a page thumbnail to go directly to that page. To change the size of the page thumbnails, from the options

menu, choose Thumbnail Size > [option].

• Drag the splitter bar at the bottom of the Compare panel up to show thumbnails of the old document. Click a

Document Description options

Reports, Spreadsheets, Magazine Layouts Compares the content as one continuous text body, from end to end.

Presentation Decks, Drawings Or Illustrations Looks at each slide or page as a mini-document, and matches ones that

are similar. Then compares the content of each matching document. Identifies documents that have moved, such as
slides in presentation.

Scanned Documents Creates an image capture of each scanned page and compares pixels. Looks at each scanned page

and matches ones that are similar. Also identifies pages that are in a different order. This option is useful for comparing
images or architectural drawings.

Compare Text Only Use this option with any document type. This option is designed for comparing text in large

documents (250 pages or more). This option also compares text between documents that have background artwork on
each page, which slows processing.

22

• With either the reports or presentation options selected, the Compare Text Only option identifies only the text

differences between two documents.

• With Scanned Documents selected, the text is compared separately from the graphics, and then the results are

combined. In documents containing magazine advertisements that have text on top of background image art, a
reflowed passage is compared in text-only mode. The artwork is compared separately in the background. The
differences (both text and line art and images) are combined into a single results document.

Preferences for viewing PDFs

The Preferences dialog box defines a default page layout and customizes your application in many other ways. For
viewing PDFs, examine the preferences options for Documents, General, Page Display, and 3D & Multimedia.

The preferences settings control how the application behaves whenever you use it; they are not associated with any
particular PDF document.

Note: If you install any third-party plug-ins, set these preferences using the Third-Party Preferences menu item.

Welcome Screen when you launch the application without a document open. Click a message to get information about
features, updates, or online services, or to open an element in the application, such as a task pane. Deselect the option
to prevent in-product marketing messages from appearing.

Note: Transactional messages, which facilitate the Adobe Online Service, cannot be turned off.

Application Startup

Show Splash Screen (Mac OS) Determines whether the application startup screen appears each time the application

starts.

Use Only Certified Plug-Ins Ensures that only Adobe-certified third-party plug-ins are loaded. The notation Currently

in Certified Mode indicates either Yes or No depending on its status.

acceleration.) When selected, allows hardware acceleration usage when the first document is opened. When deselected,
hardware acceleration usage starts after the first document is opened. This option can slow startup time, so it is
deselected by default.

25

Note: This option is available only when the option Use 2D Graphics Acceleration in the Page Display preferences is
selected.

Select Default PDF Handler (Windows only) Specifies which application, Reader or Acrobat, is used to open PDFs. This

setting applies if you have both Acrobat and Reader installed on your computer. In Windows 7 or earlier, a browser uses
this setting only if it is using the Adobe plug-in or add-on for viewing PDF files. In Windows 8, this setting controls
which application is the default PDF application for your system, including in your browser. Windows 8 prompts you
to allow this change before applying it to your system. Once set, Windows 8 also uses the selected PDF application for
tasks related to PDF files, such as previewing, displaying thumbnails, and providing file information.

Navigating PDF pages

Opening pages in a PDF

Depending on the PDF you open, you may need to move forward through multiple pages, see different parts of the
page, or change the magnification. There are many ways to navigate, but the following items are commonly used:

Note: If you do not see these items, choose View > Show/Hide > Toolbar Items > Reset Toolbars.

Next and Previous The Next Page and Previous Page buttons appear in the Page Navigation toolbar. The text

box next to them is also interactive, so you can type a page number and press Enter to go directly to that page.

Scroll bars Vertical and horizontal scroll bars appear to the right and bottom of the document pane whenever the view

does not show the entire document. Click the arrows or drag to view other pages or different areas of the page.

Select & Zoom toolbar This toolbar contains buttons and controls for changing the page magnification.

Page Thumbnails panel The Page Thumbnails button on the left side of the work area opens the navigation pane to

the Page Thumbnails panel, which displays thumbnail images of each page. Click a page thumbnail to open that page
in the document pane.

Page through a document

There are many ways to turn pages in a PDF. Many people use the buttons on the Page Navigation toolbar, but you can
also use arrow keys, scroll bars, and other features to move forward and backward through a multipage PDF.

Last updated 1/14/2015

Workspace

The Page Navigation toolbar opens by default. The default toolbar contains frequently used tools: the Show Next Page

, Show Previous Page , and Page Number. Like all toolbars, the Page Navigation toolbar can be hidden and
reopened by choosing it in the Toolbars menu under the View menu. You can display additional tools on the Page
Navigation toolbar by right-clicking the toolbar and choosing an individual tool, Show All Tools, or More Tools and
then selecting and deselecting tools in the dialog box.

Move through a PDF

❖ Do one of the following:

• Click the Previous Page or Next Page button in the toolbar.

• Choose View > Page Navigation > [location].

• Choose View > Page Navigation > Page, type the page number in the Go To Page dialog box and then click OK.

• Press the Page Up and Page Down keys on the keyboard.

Jump to a specific page

❖ Do one of the following:

• From Single Page or Two-Up page display view, drag the vertical scroll bar until the page appears in the small

pop-up display.

34

• Type the page number to replace the one currently displayed in the Page Navigation toolbar, and press Enter.

Note: If the document page numbers are different from the actual page position in the PDF file, the page’s position within
the file appears in parentheses after the assigned page number in the Page Navigation toolbar. For example, if you assign
numbering for a file that is an 18-page chapter to begin with page 223, the number shown when the first page is active
is 223 (1 of 18). You can turn off logical page numbers in the Page Display preferences. See Renumber pages and
Preferences for viewing PDFs.

Jump to bookmarked pages

Bookmarks provide a table of contents and usually represent the chapters and sections in a document. Bookmarks
appear in the navigation pane.

2 To jump to a topic, click the bookmark. Expand or collapse bookmark contents, as needed.

Note: Depending on how the bookmark was defined, clicking it may not take you to that location but perform some
other action instead.

If the list of bookmarks disappears when you click a bookmark, click the Bookmarks button to display the list again.
If you want to hide the Bookmarks button after you click a bookmark, select Hide After Use from the options menu.

Use page thumbnails to jump to specific pages

Page thumbnails prov ide mi niature previ ews of doc ument pages. You can use thumbnails in the Page Thumbnails panel
to change the display of pages and to go to other pages. The red page-view box in the page thumbnail indicates which
area of the page appears. You can resize this box to change the zoom percentage.

1 Click the Page Thumbnails button or choose View > Show/Hide > Navigation Panes > Page Thumbnails to display

the Page Thumbnails panel.

2 To jump to another page, click its thumbnail.

Automatically scroll through a document

Automatic scrolling advances your view of the PDF at a steady rate, moving vertically down the document. If you
interrupt the process by using the scroll bars to move back or forward to another page or position, automatic scrolling
continues from that point forward. At the end of the PDF, automatic scrolling stops and does not begin again until you
choose automatic scrolling again.

1 Choose View > Page Display > Automatically Scroll.

2 Press Esc to stop scrolling.

Retrace your viewing path

You can find PDF pages that you viewed earlier by retracing your viewing path. It’s helpful to understand the difference
between previous and next pages and previous and next views. In the case of pages, previous and next refer to the two
adjacent pages, before and after the currently active page. In the case of views, previous and next refer to your viewing
history. For example, if you jump forward and backward in a document, your viewing history retraces those steps,
showing you the pages you viewed in the reverse order that you viewed them.

Choose View > Page Navigation > Previous View.

1 To continue seeing another part of your path, do either of the following:

• Repeat step 1.

• Choose View > Page Navigation > Next View.

Note: You can make the Previous View button and Next View button available in the toolbar area by right-
clicking the Page Navigation toolbar and choosing them on the context menu, or choosing Show All Tools.

Navigate with links

Links can take you to another location in the current document, to other PDF documents, or to websites. Clicking a
link can also open file attachments and play 3D content, movies, and sound clips. To play these media clips, you must

If you move the PDF to a new location, the attachments automatically move with it.

Article threads

In PDFs, articles are optional electronic threads that the PDF author may define within that PDF. Articles lead readers
through the PDF content, jumping over pages or areas of the page that are not included in the article, in the same way
that you might skim through a traditional newspaper or magazine, following one specific story and ignoring the rest.
When you read an article, the page view may zoom in or out so that the current part of the article fills the screen.

Open and navigate an article thread

1 Click the Hand tool on the Common Tools toolbar.

Choose View > Show/Hide > Navigation Panes > Articles to open the Articles panel.

Note: You cannot open the Articles panel if you are viewing the PDF inside a web browser. You must open the PDF in

Use split-window view

You can view a PDF with the document pane divided into two panes (Split command) or four panes (Spreadsheet Split
command).

With Split view, you can scroll, change the magnification level, or turn to a different page in the active pane without
affecting the other pane.

The Spreadsheet Split view is useful if you want to keep column headings and row labels visible while scrolling through
a large spreadsheet or table. In this mode, changing the magnification in one pane changes the magnification in all
panes. Also, scrolling is coordinated between the panes. Scrolling a pane horizontally also scrolls the pane above or
below it. Scrolling vertically also scrolls the pane to the left or right of that pane.

1 Start creating the type of split view you want:

• To split the view into two panes, choose Window > Split, or drag the gray box above the vertical scroll bar.

• To split the view into four panes with synchronized scrolling and zoom levels, choose Window > Spreadsheet

Split.

2 Drag the splitter bars up, down, left, or right to resize the panes, as needed.

Last updated 1/14/2015

3 Adjust the zoom level, as needed:

• In Split view, click a pane to make it active, and change the zoom level for that pane only.

• In Spreadsheet Split view, adjust the zoom level to change the displays in all four panes.

4 Scroll, as needed:

• In Split view, click a pane to make it active, and scroll to change that pane only.

• In Spreadsheet Split view, click a pane, and scroll vertically to change the views in the active pane and the pane

beside it. Scroll horizontally to change the views in the active pane and the pane above or below it.

5 To restore single-pane view, choose Window > Remove Split.

View a document in multiple windows

You can create multiple windows for the same document using the New Window command. New windows have the
same size, magnification, and layout as the original window and open at the same page and on top of the original
window. When you open a new window, Acrobat adds the suffix 1 to the original filename and assigns the suffix 2 to
the new window. You can open multiple windows with the suffix incrementing with each new window. Closing a
window causes the remaining open windows to be renumbered sequentially; that is, if you have five windows open and
you close the third window that you opened, the windows are renumbered with the suffixes 1 to 4.

Note: This feature is not available when PDFs are viewed in a browser.

Opening PDFs

You can open a PDF in many ways: from within the Acrobat application, from your email application, from your file
system, or on a network from within a web browser.

Note: The Organizer and Organizer-related commands are not available in Acrobat X and later.

Open a PDF in the application

❖ Start Acrobat and do one of the following:

• Open a file from the Getting Started window. You can open a recent file or click the Open button to locate a

file.

• Choose File > Open, or click the Open File button in the toolbar. In the Open dialog box, select one or more

filenames, and click Open. PDF documents usually have the extension .pdf.

If more than one document is open, you can switch between documents by choosing the document name from the
Window menu.

Open a PDF from the desktop or within another application

❖ Do one of the following:

• To open a PDF attached to an email message, open the message and double-click the PDF icon.

• To open a PDF linked to an open web page, click the PDF file link. The PDF usually opens in the web browser.

• Double-click the PDF file icon in your file system.

Note: In Mac OS, you sometimes cannot open a PDF created in Windows by double-clicking the icon. Instead, choose
File > Open With > Acrobat.

Open a PDF in a web browser

When PDFs open in a web page, they open in Read mode. Read mode displays the PDF without the menus, panes, or
toolbars visible. Near the bottom of the window, a floating toolbar appears with basic functionality for viewing
document.

• To show the toolbar, roll your cursor near the bottom of the window.

• To page through the PDF, use the navigation buttons in the toolbar.

• To close Read mode and display the work area, click the Acrobat icon in the toolbar.

• To disable Read mode within the browser, open the Acrobat or Reader Preferences (in Windows, choose Edit >

About viewing PDFs in a web browser

Options in the web browser control how you view a PDF, either within the browser or directly in Acrobat or Reader. To
change the current display behavior, see the browser documentation on managing add-ons or plug-ins. If you open
PDFs in Acrobat outside the browser, you cannot use the preference Allow Fast Web View in a browser.

57

Because keyboard commands can be mapped to the web browser, some Acrobat shortcuts cannot be available.
Similarly, you may need to use the tools and commands in the Acrobat toolbar rather than the browser toolbar or menu
bar. For example, to print a PDF document, use the Print button in the Acrobat toolbar rather than the Print command
in the browser. (In Microsoft Internet Explorer, you can choose File > Print, Edit > Copy, and Edit > Find On This Page
on the Internet Explorer toolbar.)

Note: Having multiple versions of Acrobat or Adobe Reader installed on the same computer is not recommended. Mixed
versions on your system can prevent you from viewing PDFs in a web browser. Examples include Acrobat XI with Adobe
Reader X, or Acrobat 9 with Reader XI, and so on. For more information about coexisting installations, see this

Asian, Cyrillic, and right-to-lefttext in PDFs

Last updated 1/14/2015

Workspace

Asian language PDFs

You can use Acrobat to view, search, and print PDF documents that contain Asian text (Traditional and Simplified
Chinese, Japanese, and Korean). You can also use these languages when you fill in forms, add comments, and apply
digital signatures.

Almost all of the Acrobat features are supported for Traditional and Simplified Chinese, Japanese, and Korean text if
you install the respective Asian language font packs.

In Acrobat in Windows, you must install the Asian language support files by using the custom installation and selecting
the Asian Language Support options under Create Adobe PDF and View Adobe PDF.

PDFMaker and the Adobe PDF printer automatically embed most Asian fonts in your file when creating PDF files. You
can control whether Asian fonts are embedded.

In Windows, you may be able to view and print files that contain Asian languages without having the necessary Asian
language support installed on your system. If you try to open a PDF file for which language support is required, you are
automatically prompted to install the required fonts.

Cyrillic, Central European, and Eastern European language PDFs

You can work with Adobe PDF files that contain Cyrillic text (including Bulgarian and Russian), Central European text,
and Eastern European text (including Czech, Hungarian, and Polish) if the fonts are embedded in the PDF files. If the
fonts are embedded, you can view and print the files on any system. Fonts do not need to be embedded to use the Search
feature.

58

Note: If you open a PDF file in which form fields or text boxes contain these languages but the fonts are not embedded and
are not installed on your system, choosing Help > Check For Updates Now automatically prompts you to download and
install the necessary fonts.

Hebrew, Arabic, Thai, and Vietnamese language PDFs

Acrobat supports the entry and display of Thai and Vietnamese text. In Windows only, Arabic and Hebrew are also
supported. By default, Right-To-Left Language Options is enabled under Arabic and Hebrew regional settings (in
Wi nd ow s) .

Enable right-to-left languages

Enabling right-to-left language options displays the user interface elements for controlling paragraph direction, digit
style, and ligature. When this option is selected, you can specify the writing direction (left-to-right or right-to-left) and
type of digits (Western or Arabic-Indic) used for creating and filling out certain form fields, adding digital signatures,
and creating text box markups.

Enable Right-To-Left Language Options is enabled by default under Arabic and Hebrew regional settings.

1 In the Preferences dialog box under Categories, select Language.

2 Select Enable Right-To-Left Language Options.

Display off-screen areas of a magnified page

When you zoom in to a high magnification, you may be able to see only part of a page. You can shift the view to show
other areas of the page without changing the magnification level.

❖ Do either of the following:

• Use the vertical scroll bars to move up and down the pages or the horizontal scroll bars to move across the page.

• Select the Hand tool in the Common Tools toolbar and drag to move the page, as if moving a piece of paper on

a table.

Set the page layout and orientation

Changing the page layout is especially useful when you want to zoom out to get an overview of the document layout.
Choose View > Page Display, and select any of the following page layouts:

Single Page View Displays one page at a time, with no portion on other pages visible.

Enable Scrolling Displays pages in a continuous vertical column that is one page wide.

Two Page View Displays each two-page spread with no portion of other pages visible.

Two Page Scrolling Displays facing pages side by side in a continuous vertical column.

63

If a document has more than two pages, you can ensure that the first page appears alone on the right side of the
document pane. Select either Two Page View or Two Page Scrolling. Also select View > Page Display > Show Cover Page

In Two Page View.

You can also display buttons for each of these options in the Quick Tools toolbar by choosing View > > Show/Hide >
Toolbar Items > Page Display, and selecting them in the menu.

Note: In Single Page View, choosing Edit >Select All selects all text on the current page. In other layouts,Select All selects all

Note: The PDF opens with the page layout specified in Preferences unless a different page layout is specified in Document
Properties (File > Properties > Initial View). The Document Properties setting overrides the Preferences setting. If using
Document Properties, be sure to save and close the document for the change to take effect. Acrobat users can change the
initial view, unless security settings prevent changes. Reader users cannot change the initial view.

Use split-window view

You can view a PDF with the document pane divided into two panes (Split command) or four panes (Spreadsheet Split
command).

With Split view, you can scroll, change the magnification level, or turn to a different page in the active pane without
affecting the other pane.

The Spreadsheet Split view is useful if you want to keep column headings and row labels visible while scrolling through
a large spreadsheet or table. In this mode, changing the magnification in one pane changes the magnification in all
panes. Also, scrolling is coordinated between the panes. Scrolling a pane horizontally also scrolls the pane above or
below it. Scrolling vertically also scrolls the pane to the left or right of that pane.

1 Start creating the type of split view you want:

• To split the view into two panes, choose Window > Split, or drag the gray box above the vertical scroll bar.

• To split the view into four panes with synchronized scrolling and zoom levels, choose Window > Spreadsheet

Split.

2 Drag the splitter bars up, down, left, or right to resize the panes, as needed.

3 Adjust the zoom level, as needed:

64

• In Split view, click a pane to make it active, and change the zoom level for that pane only.

• In Spreadsheet Split view, adjust the zoom level to change the displays in all four panes.

4 Scroll, as needed:

• In Split view, click a pane to make it active, and scroll to change that pane only.

• In Spreadsheet Split view, click a pane, and scroll vertically to change the views in the active pane and the pane

beside it. Scroll horizontally to change the views in the active pane and the pane above or below it.

5 To restore single-pane view, choose Window > Remove Split.

View a document in multiple windows

You can create multiple windows for the same document using the New Window command. New windows have the
same size, magnification, and layout as the original window and open at the same page and on top of the original
window. When you open a new window, Acrobat adds the suffix 1 to the original filename and assigns the suffix 2 to
the new window. You can open multiple windows with the suffix incrementing with each new window. Closing a
window causes the remaining open windows to be renumbered sequentially; that is, if you have five windows open and
you close the third window that you opened, the windows are renumbered with the suffixes 1 to 4.

Note: This feature is not available when PDFs are viewed in a browser.

Measure the height, width, or area of objects

Use the measuring tools to measure distances and areas of objects in PDF documents. The measuring tools are useful
for showing the distances and areas associated with objects in a form or computer-aided design (CAD) drawing. You
can also use these tools to measure certain areas of a document before sending it to a professional printer. The
measuring tools are available to Reader users only if the PDF creator enables measuring functionality.

When you use a measuring tool, the Measurement Info panel shows information about the measurement, such as
current measurement, delta values, and scale ratio. Acrobat inserts comments with the values calculated for distance,
perimeter, or area.

to the second point, and click again.

• Select the Perimeter tool to measure a set of distances between multiple points. Click each point you want to

measure. Then, double-click the last point.

• Select the Area tool to measure the area within the line segments that you draw. Click each point you want to

• To snap the measurement to the end of a line, select Snap To Paths .

• To snap the measurement to the endpoint of a line, select Snap To Endpoints .

• To snap the measurement to the midpoint of a line, select Snap To Midpoints .

• To snap the measurement to the intersection of multiple lines, select Snap To Intersections

• To constrain the measurement lines to increments of 45º, hold down the Shift key.

Navigating PDF pages

Opening pages in a PDF

Depending on the PDF you open, you may need to move forward through multiple pages, see different parts of the
page, or change the magnification. There are many ways to navigate, but the following items are commonly used:

Note: If you do not see these items, choose View > Show/Hide > Toolbar Items > Reset Toolbars.

Next and Previous The Next Page and Previous Page buttons appear in the Page Navigation toolbar. The text

box next to them is also interactive, so you can type a page number and press Enter to go directly to that page.

Scroll bars Vertical and horizontal scroll bars appear to the right and bottom of the document pane whenever the view

does not show the entire document. Click the arrows or drag to view other pages or different areas of the page.

Select & Zoom toolbar This toolbar contains buttons and controls for changing the page magnification.

Page Thumbnails panel The Page Thumbnails button on the left side of the work area opens the navigation pane to

the Page Thumbnails panel, which displays thumbnail images of each page. Click a page thumbnail to open that page
in the document pane.

Page through a document

There are many ways to turn pages in a PDF. Many people use the buttons on the Page Navigation toolbar, but you can
also use arrow keys, scroll bars, and other features to move forward and backward through a multipage PDF.

The Page Navigation toolbar opens by default. The default toolbar contains frequently used tools: the Show Next Page

, Show Previous Page , and Page Number. Like all toolbars, the Page Navigation toolbar can be hidden and
reopened by choosing it in the Toolbars menu under the View menu. You can display additional tools on the Page
Navigation toolbar by right-clicking the toolbar and choosing an individual tool, Show All Tools, or More Tools and
then selecting and deselecting tools in the dialog box.

Move through a PDF

❖ Do one of the following:

• Click the Previous Page or Next Page button in the toolbar.

• Choose View > Page Navigation > [location].

• Choose View > Page Navigation > Page, type the page number in the Go To Page dialog box and then click OK.

• Press the Page Up and Page Down keys on the keyboard.

Jump to a specific page

❖ Do one of the following:

84

• From Single Page or Two-Up page display view, drag the vertical scroll bar until the page appears in the small

pop-up display.

• Type the page number to replace the one currently displayed in the Page Navigation toolbar, and press Enter.

Note: If the document page numbers are different from the actual page position in the PDF file, the page’s position within
the file appears in parentheses after the assigned page number in the Page Navigation toolbar. For example, if you assign
numbering for a file that is an 18-page chapter to begin with page 223, the number shown when the first page is active
is 223 (1 of 18). You can turn off logical page numbers in the Page Display preferences. See Renumber pages and
Preferences for viewing PDFs.

Jump to bookmarked pages

Bookmarks provide a table of contents and usually represent the chapters and sections in a document. Bookmarks
appear in the navigation pane.

2 To jump to a topic, click the bookmark. Expand or collapse bookmark contents, as needed.

Note: Depending on how the bookmark was defined, clicking it may not take you to that location but perform some
other action instead.

If the list of bookmarks disappears when you click a bookmark, click the Bookmarks button to display the list again.
If you want to hide the Bookmarks button after you click a bookmark, select Hide After Use from the options menu.

Use page thumbnails to jump to specific pages

Page thumbnails prov ide mi niature previ ews of doc ument pages. You can use thumbnails in the Page Thumbnails panel
to change the display of pages and to go to other pages. The red page-view box in the page thumbnail indicates which
area of the page appears. You can resize this box to change the zoom percentage.

1 Click the Page Thumbnails button or choose View > Show/Hide > Navigation Panes > Page Thumbnails to display

the Page Thumbnails panel.

2 To jump to another page, click its thumbnail.

Automatically scroll through a document

Automatic scrolling advances your view of the PDF at a steady rate, moving vertically down the document. If you
interrupt the process by using the scroll bars to move back or forward to another page or position, automatic scrolling
continues from that point forward. At the end of the PDF, automatic scrolling stops and does not begin again until you
choose automatic scrolling again.

1 Choose View > Page Display > Automatically Scroll.

2 Press Esc to stop scrolling.

Retrace your viewing path

You can find PDF pages that you viewed earlier by retracing your viewing path. It’s helpful to understand the difference
between previous and next pages and previous and next views. In the case of pages, previous and next refer to the two
adjacent pages, before and after the currently active page. In the case of views, previous and next refer to your viewing
history. For example, if you jump forward and backward in a document, your viewing history retraces those steps,
showing you the pages you viewed in the reverse order that you viewed them.

Choose View > Page Navigation > Previous View.

1 To continue seeing another part of your path, do either of the following:

• Repeat step 1.

• Choose View > Page Navigation > Next View.

Note: You can make the Previous View button and Next View button available in the toolbar area by right-
clicking the Page Navigation toolbar and choosing them on the context menu, or choosing Show All Tools.

Navigate with links

Links can take you to another location in the current document, to other PDF documents, or to websites. Clicking a
link can also open file attachments and play 3D content, movies, and sound clips. To play these media clips, you must
have the appropriate hardware and software installed.

86

The person who created the PDF document determines what links look like in the PDF.

Note: Unless a link was created in Acrobat using the Link tool, you must have the Create Links From URLs option selected
in the General preferences for a link to work correctly.

1 Choose the Select tool.

2 Position the pointer over the linked area on the page until the pointer changes to the hand with a pointing finger. A

plus sign (+) or a w appears within the hand if the link points to the web. Then click the link.

PDFs with file attachments

If you open a PDF that has one or more attached files, the Attachments panel automatically opens, listing the attached
files. You can open these files for viewing, edit the attachments, and save your changes, as permitted by the document
authors.

If you move the PDF to a new location, the attachments automatically move with it.

Article threads

In PDFs, articles are optional electronic threads that the PDF author may define within that PDF. Articles lead readers
through the PDF content, jumping over pages or areas of the page that are not included in the article, in the same way
that you might skim through a traditional newspaper or magazine, following one specific story and ignoring the rest.
When you read an article, the page view may zoom in or out so that the current part of the article fills the screen.

Open and navigate an article thread

1 Click the Hand tool on the Common Tools toolbar.

Choose View > Show/Hide > Navigation Panes > Articles to open the Articles panel.

Note: You cannot open the Articles panel if you are viewing the PDF inside a web browser. You must open the PDF in
Acrobat.

• To scroll through the article one pane at a time, press Enter or click in the article.

• To scroll backward through the article one pane at a time, Shift-click in the article, or press Shift+Enter.

• To go to the beginning of the article, Ctrl-click within the article.

4 At the end of the article, click in the article again.

The previous page view is restored, and the pointer changes to the End Article pointer .

About viewing PDFs in a web browser

Options in the web browser control how you view a PDF, either within the browser or directly in Acrobat or Reader. To
change the current display behavior, see the browser documentation on managing add-ons or plug-ins. If you open
PDFs in Acrobat outside the browser, you cannot use the preference Allow Fast Web View in a browser.

Because keyboard commands can be mapped to the web browser, some Acrobat shortcuts cannot be available.
Similarly, you may need to use the tools and commands in the Acrobat toolbar rather than the browser toolbar or menu
bar. For example, to print a PDF document, use the Print button in the Acrobat toolbar rather than the Print command
in the browser. (In Microsoft Internet Explorer, you can choose File > Print, Edit > Copy, and Edit > Find On This Page
on the Internet Explorer toolbar.)

Note: Having multiple versions of Acrobat or Adobe Reader installed on the same computer is not recommended. Mixed
versions on your system can prevent you from viewing PDFs in a web browser. Examples include Acrobat XI with Adobe
Reader X, or Acrobat 9 with Reader XI, and so on. For more information about coexisting installations, see this

Change updating preferences

Choose Edit > Preferences (Windows) or Acrobat/Adobe Reader > Preferences (Mac OS).

1 From the Categories on the left, select Updater.

2 In the Check For Updates section, select one of the following options for installing updates:

Automatically install updates (recommended) (Windows) Acrobat regularly checks for important updates,

downloads them, and installs them automatically. When finished, you are alerted via a small message in the system
tray that your software has been updated. This method is the best way to keep Acrobat up-to-date and more secure.

Automatically download updates, but let me choose when to install them Acrobat regularly checks for important

updates and downloads them. Acrobat prompts you to start the installation.

Notify me, but let me choose when to download and install updates Acrobat regularly checks for important

updates and notifies you. You can choose to download and install the updates at your convenience.

Do not download or install updates Acrobat doesn't check for updates. Instead, you check for updates yourself

(Help > Check For Updates). This option is the least secure and recommended only for organizations that deploy
updates using other methods.

Manage security settings

policies. Server-based security is set up by an administrator who provides the URL from which to get security updates.

1 In the Preferences dialog box under Categories, select Security.

2 In the Security Settings, select Load Security Settings From A Server.

Viewing PDFs and viewing preferences

The initial view of the PDF depends on how its creator set the document properties. For example, a document may open
at a particular page or magnification.

Note: The Organizer and Organizer-related commands are not available in Acrobat X and later.

View PDFs in Read mode

When you’re reading a document, you can hide all the toolbars and task panes to maximize the viewing area on your
screen.

The basic reading controls, such as page navigation and zoom, appear in a semi-transparent floating toolbar near the
bottom of the window.

• To open Read mode, choose View > Read Mode, or click the Read Mode button in the upper-right corner of the

toolbar.

• To restore the work area to its previous view, choose View > Read Mode again. You can also click the close button

in the floating toolbar.

Note: Read mode is the default viewing mode when you open a PDF in a web browser.

View PDFs in Full Screen mode

In Full Screen mode, only the document appears; the menu bar, toolbars, task panes, and window controls are hidden.
A PDF creator can set a PDF to open in Full Screen mode, or you can set the view yourself. Full Screen mode is often
used for presentations, sometimes with automatic page advancement and transitions.

The pointer remains active in Full Screen mode so that you can click links and open notes. There are two ways to
advance through a PDF in Full Screen mode. You can use keyboard shortcuts for navigational and magnification
commands, and you can set a Full Screen preference to display Full Screen navigation buttons that you click to change
pages or exit Full Screen mode.

Screen Mode. Then click the Full Screen tool to switch to Full Screen mode.

Touch mode for tablet and mobile devices

Touch mode makes it easier to use Acrobat and Reader on touch devices. Toolbar buttons, panels, and menus shift apart
slightly to accommodate selecting with your fingers. The Touch reading mode optimizes viewing and supports most
common gestures. Acrobat and Reader automatically switch to Touch mode when on a touch-enabled device. You can
add a Touch mode toggle button to the toolbar or change the default preference setting for Touch mode.

Change the PDF/A viewing mode

PDF/A is an ISO standard for long-term archiving and preservation of electronic documents. Documents you scan to
PDF are PDF/A-compliant. You can specify whether you want to view documents in this viewing mode.

When you open a PDF/A compliant document in PDF/A viewing mode, the document is opened in Read mode to
prevent modification. A message is displayed in the document message bar. You will be unable to make changes and
add annotations to the document. If you turn off PDF/A mode, you can edit the document.

1 In the Preferences dialog box under Categories, select Documents.

2 Choose an option for View Documents In PDF/A Mode: Never, or Only For PDF/A Documents.

You can switch in or out of PDF/A viewing mode by changing this preference setting.

For a video on working with PDF/A files, see www.adobe.com/go/learn_acr_pdfa_en.

Display PDFs in Line Weights view

The Line Weights view displays lines with the weights defined in the PDF. When Line Weights view is off, it applies a
constant stroke width (1 pixel) to lines, regardless of zoom. When you print the document, the stroke prints at the true
width.

Choose View > Show/Hide > Rulers & Grids > Line Weights. To turn off Line Weights view, choose View > Show/Hide
> Rulers & Grids > Line Weights again.

Note: You cannot turn off Line Weights view when viewing PDFs within a web browser.

Compare a revised PDF to an earlier version (Acrobat Pro)

Use the Compare Documents feature to show the differences between two versions of a PDF. You can customize many
options for displaying the compare results. For a video on comparing PDFs, see

www.adobe.com/go/lrvid_011_acrx_en. (Video applies to both Acrobat X and Acrobat XI.)

1 Choose View > Compare Documents.

2 Specify the two documents to compare. If one or both of the documents is in a PDF Portfolio, select the PDF

Portfolio. Under Package Item, select the component PDF.

3 As needed, specify the page ranges in the documents to compare in the First Page and Last Page boxes.

4 Select the Document Description that best describes the documents you are comparing, and click OK.

Once the two documents are analyzed, a results document appears with the Compare panel open. The new
document is shown with annotations indicating the changes. The first page shows a summary of the comparison
results.

5 From the Compare panel, do any of the following:

• To hide the annotations that display changes, click Hide Results.

• To specify the display options for compare results, click Show Options. You can specify the type of changes to

display, and the color scheme and opacity of the annotations. To return to the page thumbnails, click Hide
Options.

• To show each of the documents in its own window, from the options menu , choose Show Documents Tiled

or Show Documents Side By Side. To synchronize the relevant pages while showing the documents in their own
windows, from the options menu, choose Synchronize Pages.

• Click a page thumbnail to go directly to that page. To change the size of the page thumbnails, from the options

menu, choose Thumbnail Size > [option].

Document Description options

Reports, Spreadsheets, Magazine Layouts Compares the content as one continuous text body, from end to end.

Presentation Decks, Drawings Or Illustrations Looks at each slide or page as a mini-document, and matches ones that

are similar. Then compares the content of each matching document. Identifies documents that have moved, such as
slides in presentation.

Scanned Documents Creates an image capture of each scanned page and compares pixels. Looks at each scanned page

and matches ones that are similar. Also identifies pages that are in a different order. This option is useful for comparing
images or architectural drawings.

Compare Text Only Use this option with any document type. This option is designed for comparing text in large

documents (250 pages or more). This option also compares text between documents that have background artwork on
each page, which slows processing.

• With either the reports or presentation options selected, the Compare Text Only option identifies only the text

differences between two documents.

• With Scanned Documents selected, the text is compared separately from the graphics, and then the results are

combined. In documents containing magazine advertisements that have text on top of background image art, a
reflowed passage is compared in text-only mode. The artwork is compared separately in the background. The
differences (both text and line art and images) are combined into a single results document.

Preferences for viewing PDFs

The Preferences dialog box defines a default page layout and customizes your application in many other ways. For
viewing PDFs, examine the preferences options for Documents, General, Page Display, and 3D & Multimedia.

The preferences settings control how the application behaves whenever you use it; they are not associated with any
particular PDF document.
