Super Duper Power Key (change capslock, you don't use it anyway)

February 08, 2016

Brett Terpstra (a power user hero) wrote about this back in 2012, and here I am documenting my version of it (and the apps have since been renamed).

The capslock key is somewhat useless yet it takes up so much space on the keyboard. Power users (like me, ha) also have a lot of keyboard shortcuts defined and you don’t want to accidentally overwrite existing shortcut keys, so, I’ve remapped my caps lock key to be ⌃⌥⇧⌘ (that’s control, alt, shift, command) all in one go.

Then I use Alfred App to create custom commands to launch apps and run scripts based on hotkeys.

Firstly, un-map you caps-lock key from being a caps-lock key.

System Preferences > Keyboard > Modifier Keys… and set Caps Lock to “No Action”. Screen Shot 2016 02 08 at 21 14 23

Secondly, download and install Seil. Install and set caps lock key to keycode 80, which is F19. Screen Shot 2016 02 08 at 21 16 35

Finally, download and install Karabiner. Go to “Misc & Uninstall” and choose “open private.xml”. Replace the code with…

Go back to “Change Key”, reload “private.xml”, and select “F19 to F19”. Screen Shot 2016 02 08 at 21 23 29

That’s it, you’re now free to create a whole load of shortcuts without risk of overwriting anything. In the Brett Terpstra article he has the key be an escape key on short press and super duper key on long press. I took the escape bit out as I didn’t want that.

Like I said, Alfred App lets you create all sorts of commands, like toggling apps through a hotkey. Screen Shot 2016 02 08 at 21 26 43
