Capslock VS capsicain

Creating a Hyper Key (i.e., remapping capslock to become an additional modifier key) is a game changer! I use Capslock [1] with Karabiner Elements on macOS.

trigger a new meta key like ctr, but it's own set of mappings... see link https://github.com/Vonng/Capslock

Vonng/Capslock is a good demonstration of just how much you can do with the app. I use it to make caps lock Hyper/Escape and to make h/j/k/l act like Vim arrow keys when I hold down ";"

I can not use any machine without this program: https://github.com/Vonng/Capslock Make Capslock great again.

You would have to intercept the barcode scanner (keyboard) data on a low-level before all other software gets it... Maybe this could help: https://github.com/cajhin/capsicain

If you want to have layers without buying a QMK keyboard there's some software solutions like capsicain (most powerful, harder to configure, has limitations when working with wireless keyboards), Microsoft Powertoys keyboard manager (easy to configure, very limited with what you can do) that allow the same kind of functionally.

I'm not sure if this works for you: https://github.com/cajhin/capsicain

Capsicain is another one: https://github.com/cajhin/capsicain Gotta try 'em all!

For windows there is also capsicain

The mod has better split, almost orthogonal, two levels of thumb cluster, I use capsicain for this mod, find the config on this link
