Is it possible to double space as ctrl key?

[tejasvi]

I want the space key to work like Ctrl after 200 ms of being pressed. So, in theory it should work like this:

while space key is press down {
  for first 200 ms {
    if another key is pressed or space key released {
      work like normal space
      go no further
    }
  }
  after first 200 ms {
    if another key <Key> is pressed {
      Send Ctrl+Key
    }
  }
}

Is it possible with Autoit?

Hi... and welcome to the forums. FWIW, you can do almost anything in AutoIt. However, there are times where we step back and ask "Why?" before proceeding with the "How".

Can you elaborate on your situation and why you would want to use double space for control?

[tejasvi]

I am sorry I wasn't clear. I meant double as in "double meaning". My aim is to use home row keys as modifiers (here `space` is meant to be just an example) while preserving their normal behavior in most cases. Towards that goal, I want a non-modifier key to act as a certain modifier key on long press. If the key gets released before any other key presses, it should behave like the original non-modifier key.

Still not very clear to me.  But you didn't answer @Danp2 question of "why do you want to it ?".  On which application should it be applied ?
