Tangential to the content of the page: I really enjoyed how many MPW utilities generated output, including error messages, in the form of commands. Your terminal was an editor buffer, so you could cursor up (or click) on the appropriate line then press something like cmd-enter to pull up the file in question (among other things).

I think it was just the enter key to execute the selected text.

You're probably correct. I forgot that Apple labelled the enter key as return on the alphanumeric part of the keyboard and as enter on the numeric keypad. I recall some software (possibly MPW) treating cmd-return as enter. Or something to that effect. It has been about 20 years!

[cschmidt]

Yes I think you’re right. I was talking about the standalone enter key, or you could also do some modifier and return. It has been a long time

Hm. Sounds like Plan 9.
