I bought a thinkpad keyboard with the red joystick thing when I hurt my shoulder - it was only supposed to be temporary but I find myself rarely using my mouse. I’m not a great fan of the keys (especially compared to Mac keyboard).
those keyboards are great for servers or headless workstations. i have one on my thinkstation for the occasional moments where i need non-networked access. i have the usb version but they also make a wireless one.
