How can I connect to a group chat using a bookmark with jabber.el? I figured out how to look at the bookmarks via
M-x jabber-edit-bookmarks, but I can't find any commands to actually use them! (Actually editing bookmarks seems unsupported, at least in my version of jabber.el.)
I have a few bookmarks already set up with another service that do show up in the Jabber bookmarks buffer, but I have no idea of how to actually connect through them.
