Today I learned about an interesting keyboard: the mathpad.

I found the board because the keycaps are mentioned on the landing page of 3dkeycap but it's an attempt at making a specialized keyboard for Latex.

I don't write that much Latex anymore these days but I love how this macropad lets me try to coin a new term: domain specific keyboards. Because these things are getting cheap enough to prototype and design we may be entering a world where it becomes viable for specific domains to have their own board!
