Little help with AHK

Hello All,
How do I use an AHK with say “Marksman Hunter (Newest xmas GS) 12/21/15 - Patch 6.0+ - WoW Lazy Macros” macro? I have read the tutorial for AHK and its all just a mush in my head. I have been using the macro on my scroll mouse, but it still has a huge impact on my wrist. I am really trying to alleviate that pain. any help would be appreciated. Thank you all.

You can search on Google for AutoHotKey Rapid Fire to find a script and then search for the key names AHK uses and just replace the key names to whatever key you wish. You can copy and past the script over and over in the same file for multiple keys. I used AHK in this way for a long time. I hope this helps!
