Hi guys,
Don't know if this has been said before, but this might help the people who already have custom functions on their numpad (mounts for example) and would like to keep the standard keys for the notes.
To convert the keys correctly for Autohotkey to pick them up with the standard hotkeys, you have to follow the next couple of steps:
1. Open the exported song in a notepad program where you can search and replace.
2. Replace "Numpad" with "" (nothing)
3. Replace "9" with "temp" (you can fill in whatever you want, as long as it doesn't correspond with anything in the script)
4. Replace "0" with "9"
5. Replace "temp" with "0"
This will change the entire script to work with your basic keys and let's you keep your numpad nice and usable.
Hope this helps.
