Keyboard key to mouse?

[RunningBot]

Let me edit i didnt explain right ^^.

I want my side mouse click.

to act as the LShift key.

So i press Side mouse which would then simulate Lshift

Ok then.

If you tell me what you are trying to achieve with this I might be able to help you a little better.

But here is the code to make your left extra mouse button press shift.

#include <Misc.au3>

While 1==1
    If _IsPressed("5") Then
        Send("{LSHIFT}")
    EndIf
WEnd
