My keyboard for the day is a Thinkpad Compact Keyboard with Trackpoint, it's a wired USB board with an integrated mouse in a super compact layout (it started life as a laptop keyboard). It's lightweight, super low profile, the keys are nice to touch, and despite the fact it's been a decade since I touched a ThinkPad my fingers still know how and when to drive the Trackpoint.

I used these in field work for years, and dug mine out last night to work more easily on Leonard: https://digipres.club/@timixretroplays/117523283987924249
