The post key command is very useful because it simulates a key combination as if it were pressed on your keyboard. It even allows the use of more than one key mask. The following syntax shows how to simulate the Shift+Command+"P" on a Mac machine.

POST KEY (Ascii("p");shift key mask+command key mask)

As shown above, simply adding shift key mask and command key mask constants will allow the simulation of a multiple key mask.
