un-press the key even if it is being physically pressed on the keyboard

[ibieel]

Hey guys, I'm trying to put together a script that does the following:
- If the Shift, Alt or Control key is pressed, un-press the key even if it is being physically pressed on the keyboard.

I made this script:

Code: Select all

#Persistent
#NoEnv  ; Recommended for performance and compatibility with future AutoHotkey releases.
SendMode Input  ; Recommended for new scripts due to its superior speed and reliability.
#SingleInstance, Force
SetTimer, label, on


label:
While (GetKeyState("Shift", "P") || GetKeyState("Control", "P") || GetKeyState("Alt", "P")) {
   Send, {Shift Up}
   Send, {Ctrl Up}
   Send, {Alt Up}

   ToolTip, Key is Pressed
}
return

However, I am having the following problem, when the key is being physically pressed (keeping it pressed) the command "Send, {[KEY] Up}" un-press the key for a brief moment but then it is pressed again.

What can I do to fix this?

Nevermind - I misunderstood the problem.
