TouchPad Basics

The following items show you how to use the TouchPad:

• Move your finger across the TouchPad (1) to move the cursor.

• Press the left (2) and right (3) buttons located beneath the TouchPad to perform selection and
execution functions. These two buttons are similar to the left and right buttons on a mouse.
Tapping on the TouchPad is the same as clicking the left button.

Tap twice (at the same speed
as double-clicking a mouse
button); rest your finger on
the TouchPad on the second
tap and drag the cursor.

Click once.

NOTE: When using the T ouchPad, keep it - and your fingers - dry and clean. The TouchPad is sensitive to

finger movement; hence, the lighter the touch, the better the response. Tapping too hard will not
increase the TouchPad’s responsiveness.

Using the Keyboard

Your NAV50 has a close-to-full-sized keyboard and an embedded numeric keypad, separate cursor, lock,
function and special keys.

Lock Keys and embedded numeric keypad

The keyboard has three lock keys which you can toggle on and off.

Lock key Description

Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock

<Fn> + <F11>

Scroll Lock <Fn> +
<F12>

The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters
located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols
are not printed on the keys.

Desired access Num Lock on Num Lock off

When Num Lock is on, the embedded keypad is in numeric mode. The keys
function as a calculator (complete with the arithmetic operators +, -, *, and /). Use
this mode when you need to do a lot of numeric data entry. A better solution
would be to connect an external keypad.

When Scroll Lock is on, the screen moves one line up or down when you press
the up or down arrow keys respectively. Scroll Lock does not work with some
applications.
