AutoHotkey is a free, open-source scripting language for Windows that allows users to easily create small to complex scripts for all kinds of tasks such as: form fillers, auto-clicking, macros, etc.
Basically, it is a way to do a lot of different things a lot quicker.
Personally, I use it to make my life easier, for instance:
- by updating portable software,
- making hotkeys to do certain things such as media play/pause/next,
- type passwords in games that don’t allow for pasting.
Each script is basically a tekst file with a .ahk extension. The .ahk file is then run (or executed) by Autohotkey.exe, which you can download from here
A good editor that I use is Notepad ++
