Getting Started
Before AutoHotkey can do anything, you need to write a script telling it what to do.
To learn how, read the tutorial or dive straight in.
Basically: create a script file → add some hotkeys → run the script file.
You can also get help or find many useful scripts on our friendly discussion forum.
Why am I seeing this?
You ran AutoHotkey without telling it which script file to run, and it couldn't find a script in either of the usual places.
