Hello All,

What I would like to know is how to get a key press to time out.
As in you press and hold a key down while thinking, change your mind and release and so don't want it sent.

This part of a one hand keyboard project...final piece!

Thanks

Maybe something like the following (though it may be too primitive for your needs):

Code:

$Space::
KeyWait, Space, T0.2
if ErrorLevel  ; It timed out, so the key is still down.
   Send {Space}
return

If you plan to have a lot of such threads running concurrently, you should probably use SetTimer instead of KeyWait (otherwise there can be synchronization issues if many such keys are pressed and then released in a different order).

For lowercase letters the following is a very simple solution:

Code:

a::
b::
c::KeyWait %A_ThisHotKey%

a up::
b up::
c up::IfLess A_TimeSincePriorHotkey,500, Send % Chr(Asc(A_ThisHotKey))
