first of all I'd like to underline that I find most of the time documentation of AutoHotkey superb. Having this statement in mind I'd propose the following change:
In the article https://www.autohotkey.com/docs/Hotkeys.htm#AltTabDetail it is explicite mentioned:
(About special commands that are only recognized when used on the same line as a hotkey).They are not affected by #IfWin or #If.
I would suggest to put symmetric information in the article which explains #If and #IfWin directives as well: https://www.autohotkey.com/docs/commands/_If.htm
The reason for my request is that I've spent more than hour trying to figure out why #If doesn't work with AltTab special command and reading again and again about the same article. Finally I've searched Google which pointed me out to the first article quoted above.
Kind regards, mslonik
