If have an old keyboard without any of multimedia keys, it can be incredibly difficult to quickly mute your speakers.
Not a problem. Here is a simple AutoHotKey script that maps the “Caps Lock” key as a quick mute keyboard shortcut.
First install AutoHotKey if you haven’t done so already. Then type this command in a file mute.ahk, and double click to execute.
CapsLock:: SoundSet, +1, , mute
Pressing the “Caps Lock” key mutes the speakers, pressing it again restores sound.
Alternatively, you can skip all the above steps and download this executable - unzip, run and the Caps Lock key would be mapped. You don’t even have to install AutoHotKey.
