You can modify the uhk firmware quite extensively with the included Agent application. I typically stick to holding a keys to access different layers, but you can also double tap them to make it stick to a new layer. I only rarely use that functionality myself tho.

Being able to modify each button, in each layer has it's downsides tho: if I'm ever on a keyboard other than my own, I can barely type anymore!

I've edited away my most common typos on my keyboard layout, eg the key that's normally caps lock is just another shift key in my keyboard, since I find only ever use that key by mistake.

Now when I'm on another keyboard I hit it all the time, since I'm so used to it not being a problem
