Thanks, I'd missed that.

I'm trying to get dynamic (non-overlay) highlighting working in a plain
text mode.  That documentation makes me think that I just need to enable
font-lock mode, but doing that doesn't appear to make any difference.

  emacs -Q
  M-x fundamental-mode RET
  M-1 M-x font-lock-mode RET
  M-x highlight-regexp RET foo RET hi-yellow RET

  f o o SPC b a r  ;; Not highlighted, as before.

Would you expect that to work, or is there something else that I'm
missing here?  Apologies if this is a stupid question: I suspect I'm not
seeing all of the picture.

Thanks in advance,
