Function: locate-mode

locate-mode is an interactive and byte-compiled function defined in locate.el.gz.

Signature

(locate-mode)

Documentation

Major mode for the *Locate* buffer made by M-x locate (locate).

In that buffer, you can use almost all the usual Dired bindings. V (locate-find-directory) visits the directory of the file on the current line. This function runs locate-mode-hook before returning.

Operating on listed files works, but does not always automatically update the buffer as in ordinary Dired. This is true both for the main listing and for subdirectories. Reverting the buffer using g (revert-buffer) deletes all subdirectories. Specific locate-mode commands, such as V (locate-find-directory), do not work in subdirectories.
