When I first got into BSD (way before Linux) I found man pages useful... but no way to leave them. Not even man man won't tell you how to exit a man page!

So I would tinker, eventually needing a man page, reading what I needed -- and then hard power cycle the machine. -_-

I was pretty good with computers, but that was a humbling experience. You just don't know what you don't know, and if you can't ask... sometimes you just get stuck. Just like in KQ, LSL, SQ, ... The Internet is (was) a blessing.
