Can a Mql5 program "push a keyboard key" ?


I would like my mql5 code to run a key , like for example "A" anytime a specific action occurs. Is it possible ? Anybody knowing how to do it ?

Example : microsoft word is launched and the expert runs in background. any time the action occurs , a "A" will appear on microsoft word.

I've seen similar post but they were about "detecting when a key is pressed"
