question on left and right soft key


Can I please have help on a support case I have? From what I can see the Left and Right soft keys on the MT2000 are mapped to App1 and App2 respectively. I have been told that App1 and App2 map to the Operating System level as C1 and C2. Is there a way to redefine this value? Possibly through the registry? I am not looking to remap App1 and App2 but instead change the value they are assigned to at the OS level. Thank you, Amy
