Remapping caplocks to hyper key

19 October 2024 · 5min long

Here's a tip that has been a huge time-saver for me on MacOS. I only discovered it a few months ago, but it's generally well-known among self-respecting Vim developers: remapping the Caps Lock ⇪ key.

What ?

Caps Lock ⇪ key is rarely used, so why not repurpose it?

The idea is to remap Caps Lock ⇪ to an hyper key, meaning a key combination like cmd+option+ctrl+shift on Mac.

Why ?

This combination is generally never used by apps because it's too complex for users. But by mapping it to a hyper key, we gain access to an entirely new layer of shortcuts

It is mind-blowing By combining the ease of assigning shortcuts to a variety of commands with Raycast, I can now access my most-used apps super quickly.

Use cases

When I started, I've created over 20 shortcuts in less than an hour. Thanks to some mnemonic devices, there's no need to memorize them. Adopted in a flash !

I feel like I have superpowers now, accessing everything I need with just a few keystrokes.

How ?

To remap Caps Lock, I use HyperKey, which is free and made by Ryan Hanson. There might be other similar tools for Mac or Windows.

To install, download it directly from their site or use

brew install --cask hyperkey

It's a small change with a big impact for me. Give it a try !
