I remember coding on my casio scientific calculator, you could only input full keyword by selecting from a menu, it was quick and you couldn't make syntax errors.

Perhaps it was tokenising commands to save memory. Did your calculator have keystroke programming/some form of programming?

The Sinclair Spectrum Z80-based home computer had a keyboard that had all its BASIC keywords on the keyboard. I can't say I liked it, particularly as the keyboard was a very horrible rubber affair.

People are now recreating them specifically to have the same feel out of nostalgia. I actually liked them as a kid; it was so easy to write impressive (for the time) graphical programs with BASIC without remembering all these pesky english words (I am not from an English speaking country).
