I've found the best way is to copy the contents of the file into
wordpad, then save as "sniperkeys.ahk" and run it from there.
The programme you need to run this, you can download at:

Believe me - it makes text talking in the game a lot easier and allows
access to inventory items at the touch of a button.
Switching to scope and exhaling at once? That's pretty good - steady
aim straight away!
Nice one Winters!
