This AutoHotKey script fixes the Union Shapes hotkey and adds a hotkey for Subtract Shapes for Microsoft Visio. It also rebinds the common tools so that the hotkeys are all acccessible without moving your hand.
Change Notes:
(v.1.2) Added BlockInput commands to Union/Subtract Shapes hotkeys to prevent errors from user input while script runs. Removed IfWinActive command. Added Change Notes section. Renamed file to Visio Hotkey Fix
(v.1.1) Changed Subtract Shapes keybind from Ctrl+I to Ctrl+Y so as not to interfere with Set Italics default hotkey.
