The <tab> key is not normally available to Qt apps, with some exceptions
like text-entry widgets.  It is trapped by the Qt top layer and normally
interpreted as a request to switch focus to the next Qt widget.
I suppose this made sense when Qt was mostly being
used as a phone O/S but it's really annoying on the desktop.
The closest I could find to a clue how to work around this was this
thread:
   http://stackoverflow.com/questions/18160051/intercepting-tab-key-press-to-manage-focus-switching-manually

I did not try to add this to gnuplot, however, so I don't
know whether it would work for us or not.
