Because of virtual keys being messed up in the latest BETA of GM:S, I was wondering if there was a working way of simulating a keyboard press/release by tapping an object?
Use keyboard_key_press() and keyboard_key_release() in the object's Mouse Left Pressed and Mouse Left Released events? The manual claims that these functions "simulates a press/release of a key", but doesn't really detail what the scope is... check it out and see if it helps, I guess.
