I saw this on MAKE and as a long time and inveterate vim user, I kind of want one.
If you are unfamiliar with vim, it is a text editor that places control from the keyboard first and sports a couple of different modes that swap different commands for common keys, like ones dedicated to movement and editing. vim is actually the modern descendant of vi, an editor that has its roots in very slow terminal links so was designed to work well with a trickle of throughput
Adding a pedal to swap modes just makes sense once you get used to the idea of flipping your editor into different modes to accomplish different tasks. Your fingers don’t even have to leave the home row to invoke that changeover, you can just tap a foot like an F-1 racer.
