Green dot: press to display the phone keypad window or to dial a phone number (from the 
phone keypad window).

MC9090:

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.
