Hyperkey allows you to convert your caps lock key or any of your modifier keys to the hyper key: ⌃⌥⌘⇧

The hyper key acts as an additional modifier key that you can use in all of your other apps that have keyboard shortcuts

Don’t want to sacrifice a key?

Use a simple one touch gesture built just for activating the hyper key. Slide one touch down from the top edge of the trackpad to activate and remove the touch to release
