Documentation

Mark files whose tag matches REGEXP.

A tag is a keyword, a piece of meta data, associated with an image file and stored in image-dired's database file. This command prompts for a regexp, and then matches it against all the tags of all the image files in the database file. The files that have a matching tag will be marked in the Dired buffer.
