How on earth can I post system keyboard events (without getting a

As Ken mentioned, first off make sure the key has somewhere to go.
After that, this is roughly the code I use in Keyboard Maestro
(extracted bits and pieces, so it wont compile directly). My
apologies for the appearance of the code in email, but perhaps it is
still useful.
verify_noerr( ::CGEnableEventStateCombining( false ) );
verify_noerr
( ::CGSetLocalEventsFilterDuringSuppressionState
( kCGEventFilterMaskPermitAllEvents,
kCGEventSupressionStateSupressionInterval ) );
verify_noerr( ::CGSetLocalEventsSuppressionInterval( 0.0 ) );
PostModifierKeys( inModifiers, true );
verify_noerr( CGPostKeyboardEvent( inChar, inKeyCode, true ) );
verify_noerr( CGPostKeyboardEvent( inChar, inKeyCode, false ) );
PostModifierKeys( inModifiers, false );
verify_noerr( ::CGEnableEventStateCombining( true ) );
with:
void
UCGRemoteControl::PostModifierKeys( const UInt32& inModifiers,
Boolean inKeyDown )
{
if ( inModifiers&( UInt32(shiftKey) ) ) {
verify_noerr( ::CGPostKeyboardEvent( (CGCharCode)0,
kCGShiftKeyCode, inKeyDown ) );
}
if ( inModifiers&( UInt32(controlKey) ) ) {
verify_noerr( ::CGPostKeyboardEvent( (CGCharCode)0,
kCGControlKeyCode, inKeyDown ) );
}
if ( inModifiers&( UInt32(optionKey)) ) {
verify_noerr( ::CGPostKeyboardEvent( (CGCharCode)0,
kCGOptionKeyCode, inKeyDown ) );
}
if ( inModifiers&( UInt32(cmdKey) ) ) {
verify_noerr( ::CGPostKeyboardEvent( (CGCharCode)0,
kCGCommandKeyCode, inKeyDown ) );
}
}
There is an extra piece of code to release the desired key if it is
already down (if the user is pressing the A key already, and you try
to press it again without first releasing it, it wont work).
Also, the key code for A is 0. 6 is Z.
It's true on QWERTY keyboard, but you should not rely on this.
