As a Student, how do I view the keyboard controls for Video Panels embedded in an Lt Lesson?

Video Panels in Lt have no separate Toolbar for controlling Video Playback - controlling Video Panels is instead done via keyboard shortcuts.

You can view the Controls for Video Files in Lt on a Windows or Mac OS machine by mousing over the Video Window and pressing the '+' key on your computer's keyboard:
servlet.ImageServer?id=015w0000003OftL&oid=00D20000000HncM
Press the '+' key to hide the menu again.
