Bookmarks are named shortcuts for search queries. They allow using a convenient name for often-used queries. The bookmarks are also visible as shortcuts in the mu experimental user interfaces, mug and mug2.
The bookmarks file is read from <muhome>/bookmarks. On Unix this would typically be w be ~/.config/mu/bookmarks, but this can be influenced using the --muhome parameter for mu-find(1) and mug(1).
The bookmarks file is a typical key=value .ini-file, which is best shown by means of an example:
[mu] inbox=maildir:/inbox # inbox oldhat=maildir:/archive subject:hat # archived with subject containing 'hat'
The [mu] group header is required.
For practical uses of bookmarks, see mu-find(1).
