Can i create a key press with stencyl?

Ok this is a weird question. Will try to explain.
Usually a program wait for the player to press a button
But i want to know if i can do the inverse. I mean the program presses a key for the player....

Is this possible and how do i do that?

If you scroll down on the control list, there is the "simulate key press using [control]" block, which can be attached to an event.

I don't want to simulate the keypress. I want windows to detect a real keypress..... I think it is not possible but no harm asking no?

Nope, that can't be done.  Why do you want to do it though?

I see what you mean now.  That IS a simulated key press, but not for just the game window.  You want it to be simulated over the entire OS (like if you were to press the windows key on a windows computer).  I don't know what use that would have...or how it'd work with a Mac.

I can think of a bot for playing MMOPG's right?

Regardless of why, it'd be a security risk to permit it which is why it's not possible.
