However, they all perform the same basic trick of receiving one virtual key code and emitting another. Middle Tier (Quartz)Ī couple of working code examples at this level. ^ KeyBindingsEditor lets you make the above modifications. <- this article shows you 3 OSX config files that operate at an even higher level, letting you script your own mappings. However, it appears to only focus on the top tier (Cocoa/AppKit). this document is a must-see, and shows the above basic 3-tier architecture pic.

I don't see any way to disambiguate which device the keystroke is coming from.

It looks as though Apple have only overloaded certain keys, and the overloaded ones seem to get caught at a lower level. Tapping kCGEventKeyDown works for some function keys but not others.I get different keycodes for LSHIFT and RSHIFT. Yay! Modify keyDown output - that code compiles, and with minor tweaking ( CGEventMaskBit( kCGEventKeyDown ) | CGEventMaskBit( kCGEventFlagsChanged ),) I can pick up modifier keys also. Googling 'keyEventWithType CGEventTapCreate' seems like a good idea, as those are essential ingredients for Tapping the event and Re-Emitting it. I have found DDHidLib and am currently looking through it to figure out if it smoothes that problem. It is vexing that handling a key in such a useful location massively escalates the required complexity. If it were not for that awkward 75% success rate for CapsLock I would have a good solution.

Working at the bottom tier level, I can get all key up/down except for the PowerKey. Except for power, and also CAPSLOCK key-UP when it is transitioning from ON to OFF. I can intercept almost all keydown/keyup events at the bottom of the middle tier.
