4.1 Navigating In Windows CE And Applications
Graphic user interfaces like Windows CE for portable devices and desktop Windows (2000,
XP, etc.) utilize ‘point and click’ navigation. An equivalent keyboard shortcut is also avail-
able for every ‘point and click’ action.
Windows CE 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 key-
board shortcuts or touchscreen tapping.
4.1.1 Navigating Using A Touchscreen And Stylus
A touchscreen is an optional feature on 7545s. A hand-held equipped with a touchscreen
comes equipped with a stylus—a pointing tool that looks like a pen—stored in a slot at the
top of the unit. 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 7545 has a standard screen (rather than a touchscreen), choosing icons and navigat-
ing dialog boxes, displaying the desktop, and so on requires keyed input. 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: “Keyboard Navigation” on
page 70 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 76).
Note: If the touchscreen is not registering your screen taps accurately, the touchscreen
may need recalibration. Refer to “Calibrating The Touchscreen” on page 51.
Note: To prevent damage to the touchscreen, use only the stylus (pen) supplied with
your 7545.
