If you haven't already gone down the custom keyboard rabbit hole, I suspect you might like it. There's a pretty large enthusiast community out in the world, and there's a lot of ways to go custom - build your own from scratch, use a kit, use a pre-built with flashable firmware, etc.

The firmwares used (e.g. QMK) allow you to build the sort of thing you're talking about into your keyboard and more.

Custom keyboards are great. :-)

In addition to custom firmware, the other benefit is some custom keyboards have designs which are more coherent than typical keyboards. (e.g. replacing the gigantic spacebar, with more keys so that the thumbs can be more useful).

Seems like a cool thing to try! Where should someone curious like me start?
