Multi-Touch Gestures Feature
Dell™ Latitude™ XT2 Service Manual
Gestures
Gestures are expressions made while touching the screen of your Tablet PC with two fingers. They are interpreted as user commands to the operating system
or active application software. When the operating system recognizes a gesture, an icon confirming the gesture appears on the screen. This multi-touch
update includes three gestures: a scroll gesture, a zoom gesture, and a two-finger double-tap gesture. Gesture features and descriptive icons shown herein
are sourced by N-trig.
Scroll Gesture
Placing two fingers on the screen and moving them horizontally or vertically generates scrolling in the direction of movement: right, left, up, or down.
Zoom Gesture
Touching the screen with two fingers and moving them together or apart generates a zoom-in or zoom-out command to the screen.
Two-Fingers Double-Tap Gesture
Tapping the screen twice with two fingers sends an operating system command that you can configure. It can be used to perform actions, such as turning the
display off and disabling touch gestures (default), or run an executable program, such as one that opens Internet Explorer.
Sensitivity Setup
To adjust the sensitivity for the two-finger gestures, double-click the N-trig icon ( ) in the system tray, and tap the Multi-Touch Gestures tab. Set the sliders
for each gesture as desired.
