Navigating In Windows CE 5.0 
Graphic user interfaces like Windows CE 5.0 for portable devices and desktop Windows 
(2000, XP, etc.) utilize ‘point and click’ navigation. An equivalent keyboard shortcut is also 
available for every ‘point and click’ action.
Windows CE 5.0 supports the same ‘point and click’ user interface and keyboard shortcuts 
as desktop Windows with one difference—the ‘point and click’ action is accomplished 
using a touchscreen rather than a mouse. Actions can be performed using any combination 
of keyboard shortcuts or touchscreen tapping. 
4.1.1
Navigating Using A Touchscreen And Stylus
Each NEO is equipped with a stylus—a pointing tool that looks like a pen. The stylus is used 
to select objects on the touchscreen.
To choose an icon, open a file, launch an applet, or open a folder:
Double-tap the stylus on the appropriate icon.
4.1.2
Navigating Using The Keyboard
If your NEO touchscreen has been disabled, you can use the keyboard to choose icons, nav-
igate dialog boxes, display the desktop, and so on. If your unit has already been fully 
configured and your application is launched at startup, you’ll have little need for keyboard 
navigation, but you can refer to Table 4.1 for a description of the navigation keys.
Note: In order to access many of the menus discussed in this chapter, the security level 
must be set to ‘Supervisor’ (see “Security Settings” on page 57).
Note: If the touchscreen is not registering your screen taps accurately, the touchscreen 
may need recalibration. Refer to “Calibrating The Touchscreen” on page 35.
Note: To prevent damage to the touchscreen, use only the stylus (pen) supplied with 
your NEO.
