Article ID: 52808083

Symptom

Changes Do Not Take Effect When Remapping the CTRL Key to the ALT Key on the MC90xx When remapping the CTRL key to the ALT key on the MC90xx, the changes do not take effect.

Facts

MC90xx with 53-key or 43-key keypad on Windows Mobile 2003 or CE.Net 4.2

Resolution

Instead of remapping the keypad, modify the registry.
  1. On the PC, create a .reg file (for example keypad.reg) with the following contents:
[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\KEYBD]
"
ContLessVKey"=dword:f0
"ContMoreVKey"=dword:f0
  1. Copy this file into the Platform folder on the device.
  2. Cold-boot the device.  To cold-boot, hold down the power key for more than 30 seconds.
   NOTE: This does not work with CE .NET 4.1.  An option is to upgrade to CE .NET 4.2 if this mapping is needed.
