How slow?

Back in the 110-baud days (used for bad lines), when the
standard was 300-baud, RMS added a "slowly-mode" to emacs.

When a search found the next occurrence of a pattern say 50 lines
further down in a file, instead of doing the "normal" thing of 
redisplaying the entire screen at the new location, it would
instead display just ONE SINGLE LINE anew, at the TOP of the
screen.  That line of course being the line where the thing
was found.

If that wasn't the line you wanted, a subsequent ^s (equiv to
a "n" in lynx) would find the NEXT such line, and display THAT
as a single line at the top of the screen.

Only when you finally hit <return> would it redisplay the ENTIRE
screen, this time of the area around that final "accepted" found-line.

---

I still set up emacs this way today, even though locally it displays
at 9600 or more, because it saves my EYES having to search the
screen for the found line (ie, where the cursor is just then).
Keeping my eyes fixed at that top line is MUCH easier, I find.

Still easier even when the found-lines are in color, as in lynx
(although I never have gotten it to work via MY shell acct, via
kermit).

Would be a nice (optional) feature to add to lynx -- but probably
not trivial?
