I am currently compatible with two kinds of keyboards.
- ThinkPad 7-row laptop ANSI keyboard (like in T420)
- 87 keys ANSI keyboard (does not have to be mechanical) [1]
All other keyboard layouts literally does not exist for me - not matter how 'hackable' or 'open source' or configurable they are ...
