Search for my posts, I did mention it in the AHK sticky.

EDIT: My post in the AHK sticky:

I am thinking about suspending AHK using the following keys:

/ - Force disable AHK
ESC - Force enable AHK
ENTER - Toggle AHK

So basically if I hit ENTER it suspends AHK and I can type merrily and as soon as I hit ENTER or ESC it will enable AHK again.

If I start chat by typing "/" I suspend AHK and likewise hitting ENTER or ESC will enable AHK again.

Macro editing is maybe a concern. As long as I remember to hit a / though it should all be good.

Anything I am missing?

Code:
#IfWinActive, World of Warcraft 
~/::Suspend, on 
~escape::Suspend, off 
~enter::Suspend
I will have to confirm the code with my script at home but I think it works as shown here.
