Yes indeed, if you're using a delay-flag of '0' ie "trigger:0" (that will multiply 0 with 1000ms = 0s) will overwrite the default delay of '1' second between "keypresses".
Therefore this command (line)...

autohotkey.exe sendKey().ahk trigger:0 c(67):0 M:0 c(68)

...will send the string 'trigger' followed (without delay) by ASCII-char 67, the string 'M', and (without delay) ASCII-char 68.

The above script (but with that added ASCII-conversion) is available here ...

@marcos-ibarra
I'm not into AU3 that much (while knowing AHK better), what about triggering OBS's Control(s) directly, instead of Send(ing) a key in a less reliable way?

That way the window wouldn't even have to be active, only existing!

@aaaaa12345 That one was suggested a while back and I checked it out but, even with everything (mobo/NIC) configured properly, it still wouldn't work. So I couldn't recommend it.

@aaaaa12345, thanks. I've used this before and it worked great.

@juank-rojas Press [Windows]+R, type shell:AppsFolder in the Open text box and you will find all shortcuts of installed applications. Then you copy the whatsapp shortcut to the desktop of your computer. Then click with the right mouse button and copy the "Local" which will look something like this: “C:\Users\replace as your username\Desktop\WhatsApp.lnk”. Then with this path you create it in Trigger and it works. In my case it worked! See the post: Need a command to open apps on my pc, like games, Spotify or Netflix! Its URGENT | TRIGGERcmd Forum

@jakesmith46001
thanks, it worked very well

@oscar-mro Hello friend, here on my machine, it is not clicking on Tab and space

@chaim-tscholkowsky, I see your command's name is "outside" but its voice field is blank. Please try again after you set that to "outside".

If it still doesn't work, you could try switching to the TRIGGERcmd Smart Home skill instead of the TRIGGERcmd skill.

The Smart Home skill works better, but you'll need to treat it like an on/off switch and say something like this instead:
Alexa, turn on outside. or Alexa, turn outside on.

@russ Thankyou!

@russ Tranks!!!!!!!

@p2p, you should make it a foreground command.

If you're trying to have Windows automatically logon during boot, you should use this method instead.

@russ and that's the diference between a junior developer and a senior one.
Thanks Russ, it worked with the quote!
