While formally saying mnemonics should not work on Mac and considered bad UI design due to Apple guidelines (see
http://developer.apple.com/documentation/Java/Conceptual/Java14Development/07-NativePlatformIntegration/NativePlatformIntegration.html
), still are convinient keyboard helpers in various modal (and modalless) dialogs where otherwise user enforced to use the mouse.
Right now Alt+<letter> combinations are intercaught by Apple input method processing handlers to insert various special characters into text fields being in focus instead of activating mnemonc-enabled control.
Requested functionality:
Provide an option that being switched on (enable mnemonics) will take precedence over native input method processing in favor to activating mnemonics.
Whenever this options is switched off (default?) no mnemonic visual indication should appear in user interace.
If I understand this document correctly, only mnemonics for JMenuItems are
considered bad UI design on Mac (although I don't share this experience).
