Return from Model Panel executes command three times(!)

[goddard@…]

The following bug report has been submitted:
Platform:        Darwin-19.2.0-x86_64-i386-64bit
ChimeraX Version: 0.92 (2020-01-22)
Description
If I hit the return key after clicking into the model panel my command (which is slow, takes 0.8 seconds to execute) gets executed 3 times (I see 3 models created instead of 1).  If I click in the command-line and press Enter the command executes just once.

The main UI and tools were forwarding the same keystrokes to the command line

Beautiful!  Fixes my test case.
