Based on some of the responses we have gotten, I think we are
configuring the notebook so that this doesn't work.  I will play
around with the config to see if I can get this to work.

Yes, this is likely a problem with the python mode.  It is very likely
it can be fixed.

There is a search and replace demo for CM here:

Fernando, if we can fix these things, are you open to using CodeMirror
always?  Would you still want the ability to do the full-window-like
editing mode?
