Some keybindings are just missing in the Folder tree pane, chief among
those is Home and End. These should select the root of the first
account and the last folder in the last account, respectively. I find
myself using repeated PgUp and PgDown instead, which almost works (but
also makes the absence of Home and End even more inexplicable :)
Also, a binding to select the parent of currently selected folder node
(analogous to what default binding of Ctrl-Up does in the message
summary pane) would help a lot.

Add a menu teim for going to parent folder
So apparently Ctrl-Home and Ctrl-End works in the folder pane (I
believe those are Gtk default keybindings). Scratch that part.
For the "jump to parent folder" part, see (and apply, hopefully)
the attached patch, which adds an item to the View/Go To menu to
do just that.
Both Home and End keys now work as they should in folderview, and you can use Left key to move cursor to parent folder.
I do not think adding a keybinding for actual selecting parent folder is a good idea. If anything, Ctrl+Up should probably be made to work in folderview if that's where cursor focus is.
