### Searching source files

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`.
