ALPHA key and then press the '6' key three times to produce the letter 'r'.
When the SHIFT key is pressed in Alpha state, the upper case alphabetic characters on the

On Windows Mobile 5.0 devices: 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 keys to an application,
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.
Note: Other applications cannot receive any key event until GXCloseInput() is called. For
example, if the customer is using the APP1 key to run Calc.exe, this is disabled during this
period.
