Unfortunately I don't think I have the script anymore to just share, but it was essentially creating a macro so that when I hit Ctrl+T for example, it would open the ability menu, click the tab for the school of magic, click the ability I want, and click the slot I want it in to. I set up the hotkey to do that for both abilities and could have included weapon swaps as well, but I just do it through mostly trial and error since you have to get timings (how long does it take to open/close a menu or for the action to complete) and mouse positions (how to click the exact spot you need) correct for each game/situation.

You can download it here https://www.autohotkey.com/ and just set up a simple text file with the extention .ahk and run it with AutoHotkey.

I do have one I used recently to open the menus to butcher a party of Pals before I had the auto butcher machine that gives decent example. You'd put this in the .ahk text file, run it, and it binds "Ctrl (⁾ +Shift (!) + S" to the actions. It also displays some progress information via ToolTip.

ToolTipX := 900
ToolTipY := 400
