I can't believe such simple functionality would be missing from ahk, but I couldn't find this in the help file or forum search:

How to make a hotkey subroutine run only on a real keypress, not on ones generated by key repeat (typematic)? Using a state variable for each such hotkey would be just inelegant and redundant as the WM_KEYDOWN message already contains repeat count and previous state bits.

Something like this?

Code:

$a::
  Send, a
  KeyWait, a
Return

Code:

Loop, 26
  HotKey, % "$" Chr(A_Index+96), myLabel
Return

myLabel:
  Send, % SubStr(A_ThisHotkey,2)
  KeyWait, % SubStr(A_ThisHotkey,2)
Return

Ah, true, the KeyWait function is likely sufficient for my needs, :) but that's still a workaround; i.e. based on suspending threads and still discarding the keyrepeat status bits. Your example would still activate if I start the script in the middle of holding down 'a'. :P

Actually, the keywait method is seriously flawed, since AHK is essentially single threaded.

Consider for instance the following:

Code:

$*a::
Send, {blind}{a down}
KeyWait, a
Send, {a up}
return

$*s::
Send, {blind}{s down}
KeyWait, s
Send, {s up}
return

It's supposed to disable typematic for a and s keys. Simple enough? But it fails when using the keys simultaneously. E.g. pressing
a down, s down, a up
should trigger the "Keywait, a", but there's actually only a single thread waiting on the "KeyWait, s". Therefore, tapping a while holding s does nothing!

You can use GetKeyState.

Code:

$*a::
If !GetKeyState("a") ;if "a" is not down
 Send, {blind}{a down}
Return

*a Up::
Send, {a up}
return

$*s::
If !GetKeyState("s")
 Send, {blind}{s down}
Return

*s Up::
Send, {s up}
return

Sorry, I guess my post was slightly misleading. Basically I want to disable typematic for hotkeys with arbitrary functionality, not just simple key down/up ones. I.e.

Code:

*key1::
If (keypress is from typematic)
   return
Myfunction1()
return 

So is the following combination really the only way to accomplish this?

Code:

*key1::
If (hotkey1_active)
   return
hotkey1_active := 1
Myfunction1()
return

*key1 up::
hotkey1_active := 0
return
