There are two commands for searching through the current source file for a
regular expression.
forward-search regexp, search regexp
The command forward-search regexp checks each line,
starting with the one following the last line listed, for a match for
regexp. It lists the line that is found. You can use the
synonym search regexp or abbreviate the command name as
fo.
reverse-search regexp
The command reverse-search regexp checks each line, starting
with the one before the last line listed and going backward, for a match
for regexp. It lists the line that is found. You can abbreviate
this command as rev.
