How to control the top and bottom lamps

The Top and Bottom lamp buttons are located in the upper right corner of the main window. These lamp buttons control their respective lamps on the microscope.

If the top lamp is on and the Bottom lamp button is clicked the top lamp will turn off and the bottom lamp will turn on, if the bottom lamp is on and the Top lamp button is clicked the bottom lamp will turn off and the top lamp will turn on.

The top and bottom lamps can also be toggled on and off with the following keyboard shortcuts
  shift-command-t for the top lamp
  shift-command-b for the bottom lamp

If the microscope is out of its cradle, only the top lamp can be turned on and off.
