How are Mnemonics On Buttons Supposed To Work?

[Mark Fortner]

Hi John,
Yes, I am using OS X. Thanks for the link.   I ended up creating a window
level key listener to listen for single key press events (don't really need
a modifier).  I'll have to rethink my approach.

It would be nice if there was a note in the javadoc about this.

Regards,
Mark

Cheers,

Mark
