The BBC Microcomputer had an "Escape" key and a potentially misleadingly named "Break" key - but "Break" was actually more like a reset key (with CTRL-Break being a "harder" reset and SHIFT-Break prompting the computer to boot off a floppy disk).
But one nice feature was that if you were simply programming in BASIC and immediately typed OLD after hitting "Break", you had a chance of recovering your program if you weren't unlucky.
And the other feature which this comment reminded me of - at least some models of the BBC Micro had a hardware lock on the "Break" key, so with a small screwdriver you could turn a little piece of plastic to completely prevent the key being pressed!
