I have sorta tried this.

Razer makes a macro keypad which they call "orbweaver" and it also has a nifty thumb switch which I suppose they intended to be used for the wasd movement in games. Unfortunately, it's designed to be used with the left hand and I mouse with my left hand. I would dearly love a macro keypad exactly like an orbweaver but which was designed for use with the right hand.

So I also now own an unbranded "ambidextrous" macro keypad. Besides the fact that it is great example of how ostensibly ambidextrous devices being really not that great for left handed people, I mostly used it for gaming but as I am not much of a gamer it doesn't get used often.

I also migrated from a Mac desktop to Linux. I had a very nice application for macros on MacOS called ControllerMate but I've yet to find anything remotely similar for Linux.
