Chapter 1: Workspace

Workspace basics

Workspace overview

Adobe Acrobat DC user interface has three views - Home, Tools, and Document.

Home This is the gateway or the landing page when you don’t have a PDF opened in Acrobat DC.

Tools This is the go to place to discover the tools that’s available in Acrobat DC. All Acrobat DC tools are shown in this

view.

Document This is the default view whenever a document is opened in Acrobat DC.

Home view

This is the gateway or the landing page when you don’t have a PDF opened in Acrobat. When you launch Acrobat, you see a welcome message with the Learn More button pointing to a quick introduction document.

The Home view displays two file lists - Recent and Sent. All your recently accessed files are displayed in the Recent file list, and all the files that you sent using Adobe Send & Track and Send for Signature are displayed in the Sent file list.

The Storage option lists various places from which you can open and work on files from within Acrobat - My Computer, Document Cloud, and Add Account(a SharePoint account).

In the Home > Recent files list, you can:

• See your recently used files, and also sync them across devices using the Mobile Link option at the bottom of the

righ pane.

• Access your files stored securely in Adobe Document Cloud uisng the Document Cloud link in the left pane.

• Add SharePoint accounts using the Add Account link in the left pane.

This is the go to place to discover the tools that’s available in Acrobat. All the tools are shown in this view. When you choose a tool, the tool-specific commands or toolbar appears in the document view if a file is opened.

Note: You can also open some tools even without opening a document. If the tool requires a document to be open, choosing a tool prompts you to select a document.

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

Initially, you may not see various tools in the toolbar. You can add tools to the toolbar for easy access.

To add tools in the toolbar, right-click an empty space in the toolbar and choose the tools that you want to appear in the toolbar.

Set preferences

Many program settings are specified in the Preferences dialog box, including settings for display, tools, conversion, signatures, and performance. Once you set preferences, they remain in effect until you change them.

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

2 Under Categories, select the type of preference you want to change.

Restore (re-create) preferences

Restore the Acrobat Preferences folder (Windows)

Restore the Acrobat Preferences folder to eliminate problems that damaged preferences cause. Most preference problems are caused by these file-based preferences, although most Acrobat preferences are stored within the registry.

Note: This solution removes custom settings for Collaboration, JavaScripts, Security, Stamps, Color Management, Auto Fill, Web C aptur e , and Up d ater.

1 Quit Acrobat.

2 In Windows Explorer, go to the Preferences folder:

• (Windows 7/Vista) C:\Users\[username]\AppData\Roaming\Adobe\Acrobat\[version]

• (XP) C:\Documents and Settings\[username]\Application Data\Adobe\Acrobat\[version]

3 Move the Preferences folder to another location (for example, C:\Temp).

4 Restart Acrobat.

If the problem recurs after you restore the Acrobat Preferences folder, then the problem isn’t related to the Preferences folder. To restore custom settings, drag the folder you moved in step 2 back to its original location. Then click Yes To All to replace the new Preferences folder.

Restore the Acrobat preferences files (Mac OS)

Restore the Acrobat preferences files to eliminate problems caused by a damaged preferences file.

Note: Re-creating the Acrobat preferences files restores settings to their defaults.

1 Quit Acrobat.

2 Drag the following files from the Users/[Username]/Library/Preferences folder to the Desktop:

• Acrobat WebCapture Cookies

• com.adobe.Acrobat.Pro.plist or com.adobe.Acrobat.Pro_x86_9.0.plist

• Acrobat Distiller Prefs and com.adobe.Acrobat.Pro.plist (if you are troubleshooting an issue with Distiller)

• The Acrobat folder, which contains preferences for forms (MRUFormsList), collaboration (OfflineDocs), and

color settings (AcrobatColor Settings.csf)

3 Restart Acrobat

If the problem recurs after you restore the Acrobat preferences files, then the problem isn’t related to preferences files. To restore custom settings, drag the files you moved in step 2 back to their original location. Then click OK to the alert “A newer item named ‘[filename]’ already exists in this location. Do you want to replace it with the older one you're moving?”

Mobile Link: open once, read anywhere

Access your recent files across all devices using Mobile Link

With the new Mobile Link feature, the files you opened recently on any of your computers or mobile devices are always with you. You can also access your recent files by signing in to your Adobe Document Cloud account using a web browser.

When you enable the feature on any one of your devices, the PDF files that you opened recently are available in your recent file list wherever you are. Sign in on all your devices to access the up-to-date recent files list. Reader/Acrobat automatically uploads your recently viewed files to Adobe Document Cloud in the background and synchronizes the recent files list among all your devices. When you open a file from the list, Reader/Acrobat downloads the file in real time if it’s not available locally, and then displays the file.

Note: The Mobile Link feature is not available in Reader and Acrobat on Windows XP.

Enable Mobile Link

Tu r n Mobile Link ON from any device and it's ON everywhere. Simply sign in on your other devices or at

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.

Last updated 4/7/2015

Workspace

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.

Set the Full Screen navigation bar preference

1 In the Preferences dialog box under Categories, select Full Screen.

2 Select Show Navigation Bar, then click OK.

3 Select View > Full Screen Mode.

The Full Screen navigation bar contains Previous Page , Next Page , and Close Full Screen View buttons. These buttons appear in the lower-left corner of the work area.

Read a document in Full Screen mode

If the Full Screen navigation bar is not shown, you can use keyboard shortcuts to navigate through a PDF.

Note: If you have two monitors installed, the Full Screen mode of a page sometimes appears on only one of the monitors. To page through the document, click the screen displaying the page in Full Screen mode.

Choose View > Full Screen Mode.

1 Do any of the following:

• To go to the next page, press the Enter, Page Down, or Right Arrow key.

• To go to the previous page, press Shift+Enter, Page Up, or the Left Arrow key.

Touch mode for tablet and mobile devices

Touch mode makes it easier to use Acrobat DC and Acrobat Reader DC 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 DC and Acrobat Reader DC 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.

Display Touch mode button on toolbar

You can display a toolbar button to toggle Touch mode on and off.

❖ Choose View > Show/Hide > Toolbar Items > Touch Mode.

Set Touch Mode preference

You can set how Acrobat DC enters Touch mode, if at all, for touch enabled-devices.

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

2 Under Categories, select General.

3 In Basic Tools, choose the desired default setting from the Touch Mode menu.

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 DC)

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].

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

thumbnail from the old document to open it in a new window.

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.
