[chimera-dev] accelerators and stereo

[Thomas Goddard]

Hi Matthew,

  Here is a modification of the ChimeraExtension.py code I sent
earlier that will make the F1 function key switch between stereo and
mono viewing.  It directly grabs the F1 key presses from the main
Chimera window since our current accelerator mechanism is ignoring the
function keys.  This code still provides the menu entry
Tools->Utilities->Stereo/Mono and allows you to add a toolbar button
as I described previously.

  To use this code make a directory in your Chimera distribution
chimera/share/Stereo (directory name does not matter) and put the code
below in a file ChimeraExtension.py (name does matter).  This will add
the F1 function key binding and the Tools->Utilities->Stereo/Mono menu
entry to toggle modes.

      Tom
