13.8 Speedbar

speedbar is an Emacs-extension that shows navigational information for an Emacs buffer in a separate frame. Using mu4e-speedbar, mu4e lists your bookmarks and maildir folders and allows for one-click access to them.

To enable this, add (require 'mu4e-speedbar) to your configuration; then, all you need to do to activate it is M-x speedbar. Then, when then switching to the The main view, the speedbar-frame is updated with your bookmarks and maildirs.

For speed reasons, the list of maildirs is determined when mu4e starts; if the list of maildirs changes while mu4e is running, you need to restart mu4e to have those changes reflected in the speedbar and in other places that use this list, such as auto-completion when jumping to a maildir.
