This program was built using AutoHotKey v1.1.28, which is a comprehensive scripting wrapper around the Windows API. It will therefore probably run on Windows XP or above, though I've only tested on Windows 10. This also means it is very much a Windows exclusive; comparable programs can probably be made for Mac and Linux but I have no intention of doing so any time soon. Feel free to link to other programs that do something similar for whatever operating system.
