Reproducible: Steps to Reproduce:
(( Bugzilla died on me when posting ... re-adding original content )) Please add a keybinding for F9 to toggle the visibility of the side pane. When you have multiple views for the side pane (bookmarks, tree, ..), each with their own keybinding (^B, ^T, ..), F9 just hide/shows whatever happens to be the current view in the side pane. Although this keybinding is not in the HIG it is found in a number of Gnome programs like nautilus, evince and totem and thus it can be argued that it should be added for general consistency.
