Key Description
Power (red) Turns the mobile computer on and off.
Performs a warm boot and a cold boot. See
Windows Mobile 5.0 Devices on page
2-18
for information about performing a warm and cold boot.
Green/Red Dot To use a key as an application key (APP key) on the keyboard, a new keyboard
remap table must be created and installed. However, the Green/Red dot keys can be
remapped as APP keys through the registry.
Create an XML Provisioning file with the following entries:
Characteristic type
=“HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\KEYBD”
Parm name = “GreenKeyOverride” value = “xx”, where xx is the new APP key code.
Parm name = “RedKeyOverride” value = “xx”, where xx is the new APP key code.
Refer to the MC909X Integrator Guide for instruction on updating the registry using
XML Provisioning.
This sends an APP key code, instead of their original key codes, when the green or
red dot key is pressed.
Scan (yellow) Activates the scanner/imager in a scan enabled application.
Scroll Up and Down Moves up and down from one item to another.
Increases/decreases specified values.
Scroll Left and Right Moves left and right from one item to another.
Increases/decreases specified values.
ESC Exits the current operation.
Alpha Use the alpha keys for alphabetic characters.
SPACE/BKSP Space and backspace functions.
Numeric/Application Numeric value keys - can have applications assigned with function key(s).
The
F6
and
F7
keys cannot be remapped and are dedicated by the Operating
System to control volume level. When these keys are pressed, Shell.exe traps them
and displays the volume adjustment window. To get these k eys to an appli cation, call
GXOpenInput() at the beginning of the application and call GXCloseInput() at the
end of the application. This redirects all of the key events to an application, including
the
F6
and
F7
keys.
