Bug 24759

Issue 19156 talked about Term not having shortcuts
for moving left and right. for a while that bug
was treated as a tip'o the iceberg for all lack
of shortcuts for the Term/OW combo. Most of
that is taken care of but managing the selection
isn't done yet. Since I"m closing that issue I'm
opening this one.

The plan of record until recently was as follows.
Unlike JText the cursor in Term plays no role in 
the boundary of the selection so a new cursor, a
vertical line, has to be invented. Normally it
will hide beneath the regular cursor. As soon as
you use a shortcut to manipulate the selection it
separates and works per JLF2 p259.
The only problem with this is removing the
selection, (sending the selection cursor "home").
There is Ctrl-\ to deselect all however it's the
keyboard sequence that on unix generates SIGQUIT 
and that won't be very good.

An alternative proposal hasfor a modal scheme not
unlike Microsoft Windows console, but I haven't
fully investigated that. 

Another model might be what Gnome has adopted for
it's termulators, but I haven't found out what
that is yet.
