Any time you find yourself repeating a big long conditional like > + if (([event modifierFlags] & NSEventModifierFlagControl) && > + ([event modifierFlags] & NSEventModifierFlagOption) && > + ([[event charactersIgnoringModifiers] length] == 1) && you should take a step back and say "how can I avoid repeating this?". In this case, all you need to do is delete the "else" from the start of } else if (qemu_console_is_graphic(NULL)) { All the specially-handled ctrl-alt combos finish with "return", so all the rest will then just fall through as required. I've put a patch which does that into cocoa.next. thanks -- PMM

Send control-alt key combinations to the guest if not used by the user interface.
