Wow! For a "modeless" editer, emacs sure has a lot of modes!
In any reasonable vi clone (e.g. nvi, vim, elvis, etc.) you have
basically two modes: insert and command. If your in insert, hit
the escape key to get into command mode. Then just type a colon
":" and enter "%s/<text to replace>/text to replace with/g".
This is pretty standard syntax for this sort of thing in unix.
The "%" is a short cut for specifying all lines in the file which
could be done with "1,$" longhand. The "s" is "swap" or
"switch" or something like that. The first slash marks the
begginning of the search text. The second slash separates that
from the replacement text and the last ends the text spec. The
"g" indicates a global operation for each line specified (in this
case all lines). The global specification is needed if you want
all incidents of the search text on each line replaced. So, in
vi just type:
:%s/<whatever>/<whatever else>/g
Very simple.
The text can contain pretty much anything, but some stuff may
need to be esaped with a back slash "\" or input "as is" with a
^V<character>.
Outside of that, I'm sure there must be some handy HTML editors
that can do this as well.
