Comment 1 for bug 482490

This should probably also allow adding to the top/bottom of the current branch... so, instead of a single hotkey, perhaps it should be a key sequence:

  - a key to initiate the action, possibly followed by a key to indicate [t]op or [b]ottom
  - a key to specify [f]ile or [p]arent (or maybe [b]ranch)
  - and then the UI allows the user to enter a title.

I'm not sure whether the first key should also specify top/bottom. It would be nice to use 2 keys instead of 3, but that would require allocating two top-level key bindings instead of just one.
