Trying to make a script that spam keystrokes while the other key is held down

So im trying to make a script that spams "a" key while the LShift key is held down when i press the trigger key.

Code: Select all

F3::
if (enable := !enable)
    setTimer, routine, -1
return

routine:
while enable
{
    send {LSHIFT down}
    Random, r, 50, 200
    sleep r
    sendInput a
}
return

this is my code. it works well but it just doesn't stop when i press f3 again. it stops when i'm deleting the line " send {LSHIFT down}", so this must be the problem.
it is important to send strokes while the shift key is held down so don't tell me use "sendInput +a". also it needs to send the strokes at random intervals.

It also need to hold down the shift key in the progress. not "shift down" "send keystroke" "shift up".
