I have following setup:-We are using oracle database 11gR2
You will need to define your custom key map in the key mapping file you use. Typically fmrweb.res or fmrpcweb.res. Edit the file in a text editor and take a look to figure out where you need to make the change.This is wrong! The OP is talking about the Access Key (key mnemonic's) of a button. This has nothing to do with the mapping of keys in the frmweb.res, etc., files.
