title: Toggle a key with hotkey in autohotkey
body: <p>So I tried to automate running in a game, where the map is huge, and I have to run miles. I wanted to toggle on the hotkey (<kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>A</kbd> or something else) press the running (in the game, I can run with <kbd>w</kbd>).
  I tried code, like:</p>
  
  <pre><code>Pause On
  Loop
  Send w
  +^a::Pause
  </code></pre>
  
  <p>(it can press the w, but it can't release) and like this:</p>
  
  <pre><code>+^a::
  toggle := !toggle
  
  while toggle
      Send {w down}
  </code></pre>
  
  <p>(same problem).
  It's just my problem, or these codes are wrong?</p>
