What is the right way to send Alt + Tab in Ahk?

Question

Ok. I know this is a very stupid question. But I'm stuck already for an hour.

I got very little experience with ahk, however I made work every script until now with no problems. I explored the ahk tutorials but found no solution up to now.

I'm trying to switch to prev. app with a single numpad off key. I've tried:

!{Tab}

,

{Alt down}{Tab}{Alt up}

I've tried it with Sleep delays, multiline, multiline inside brackets, with and without commas after commands, etc.

I'm quite sure is very simple but something I've not tried yet.

Any suggestion?

EDIT (suggested by the user Ooker):

The script pops up a menu for you to choose.

This is what it looks like:
