IDEA: Mouse click macro

[loopax]

Can someone tell me please if it is possible to make a macro so when the left mouse button is pressed to send a key also ?
-to make it simple ... click -> send key "A" once, only when the mouse button is pressed

thanks

Here's an AutoHotkey script that send a when the left mouse button is clicked, but how is this useful?
