If you ever used MPW shell, a lot of those characters were part of the syntax of commands and the regular expression parser so it was common to learn to compose ∫,® ∂ etc. The debugger TMON also used them, so they just become second nature, like !@#.

Neat, did not know that. At the time MPW shell was used, it was a little bit too advanced for me — I was only as far as working my way through C For Dummies (or something like that) with a limited student edition of CodeWarrior* around the time REALbasic came out.

* Possibly bronze edition? Whatever it was, it was 68k only.
