Ah, a recursive solution. Elegant!

With HJKLYUBN unlike these modern savages with their arrow keys.

How do they fly, or efficiently enter strings of numbers?

Some keyboards let you hold down a FM key to use some normal keys as a numpad, but not enough.

many enthusiast keyboards are “tenkeyless” precisely because the numpad is too far from the home row to be actually useful when you get efficient typing patterns worked out

i have a tenkeyless and use programmers dvorak (which is honestly imo pretty brain dead for its use of the num row and still is “fine” for numbers): you get used to it very quickly, and typing numbers with the numpad as an efficiency improvement is more than made up for by using both hands on the num row, and by it being far closer to the home row

that TV is a prime candidate for /tvtoohigh and also needs its own sub/comm for /tvwaaaaaytooclose, despite the mild “improvement” to the original image
