I’m a big advocate for the hyper key. This idea was first introduced to me by Brett Terpstra and involves mapping Shift-Control-Option-Command to the caps lock key. Using the hyper key opens your keyboard up to a ton of new easily triggered shortcuts. Historically, I’ve done this remapping with Karabiner Elements. However, this remapping just got a lot easier. BetterTouchTool has added the a new feature that lets you map the hyper key combination to any key (including caps lock). See the screenshots below for how to set it up. Also, the developer has a walkthrough right here.
