I have been using UNIX and Linux for over 25 years and did not realize
X11 has four clipboards. I recently discovered the Secondary Selection
keyboard.
It really saves a bunch of time when I am programming as I don't lose
my cursor's hot spot.
Here is a great 8 minute video demonstrating all four clipboards. It
is must learn for anyone using Linux.

To support this clipboard, your program has to use the GTK Toolkit.
Thanks. I didn't know about this secondary clipboard. I've just tried
it on my laptop running Ubuntu 17.10 but it didn't work. I suspect
that it's been deep-sixed in Gnome Shell and Unity.
I was interested in the secondary clipboard too, and looked at
http://www.cs.man.ac.uk/~chl/secondary-selection.html
which makes clear that this is not a standard gtk feature;
there are experimental modified gtk3 libraries which support
secondary selection (no source yet).
gtk3 means it doesn't run on SL6, so I haven't been able to explore
further.
