You can navigate Containers using the keyboard rather than using the mouse using the following keys:
- Alt-Left: Moves back to previously viewed Container
- Alt-Right: Moves forward (only active if you have already moved back
- Alt-Home: Moves up to the model root
- Alt-Up or Alt-PgUp: Moves up one level
Note also that a Container can be entered via a Ctrl-left click (in addition to clicking on the + sign in the upper left hand corner of the Container icon).
