WOW. I knew that AutoHotKey could be used to allow us to fill in gaps in the "wish there was a key for this" list. But yours is way beyond what I could have done. and THANKYOU for the extensive documenting in the file. I look forward to more from you.
Maybe you can browse the wishlists?
On the windows thing..
I started my scripts with a mass of mouse movement toward the upper left corner of the screen. More moves than I would ever need. Then movement from there would always be relative. Altho I admit I never tested it in multiple screen sizes so I have no idea how that would affect it.
One that I did was for an RPG game of Dom3. It created the same god over and over and over so that I could finally get one with random titles that I felt I could role play. It was fun to watch it generate 20 gods in the blink of an eye.
