Returns true if the shift/ctrl/alt key is currently depressed.
shiftDown = IsShiftKeyDown(); ctrlDown = IsControlKeyDown(); altDown = IsAltKeyDown();
- 1 (true) if the given key is currently held down, nil otherwise.
- MODIFIER_STATE_CHANGED - fires when shift/ctrl/alt keys are pressed or released
if ( IsShiftKeyDown() ) then DoSomething(); end
These functions will only return true if one of the keys is considered a modifier. If the code executing is started with Shift/Control/Alt as part of the key binding, it will return nil. Govtgeek (talk) 01:30, 8 March 2009 (UTC)
