There is also the J language [1], which I understand to be a GPL reimplementation of APL. Since they went with pure ASCII, you presumably have to hold down modifier keys less.

I never used either language, so can’t comment on how useful they are. But I’ve always been fascinated with APL as an idea, especially after watching this [2] person implement Game of Life as a compact one-liner in APL! (With that compact code, maybe you press modifiers less overall than when writing more traditional/verbose languages?)
