hi all,
thanks for the help
the characters message gives me the unicode output, that is working fine
but i am unsure how to detect raw keys, like arrow keys, function keys, etc
in carbon/event manager there was charCodeMask and keyCodeMask which
determined this stuff
what is the best way on cocoa to determin raw key (physical key) input?
thanks,
bill appleton
