I never entirely figured out what they are but if you try "man xclip"
I guess I was thinking of selection, 
https://wiki.archlinux.org/index.php/Clipboard#Selections

The majority of programs for Xorg, including Qt and GTK applications, follow this behavior. While ICCCM also defines a SECONDARY selection, it does not have a consensually agreed upon purpose. Despite the naming, all three selections are basically "clipboards". Rather than the old "cut buffers" system where arbitrary applications could modify data stored in the cut buffers, only one application may control or "own" a selection at one time. This prevents inconsistencies in the operation of the selections.


       -selection
              specify which X selection to use, options are "primary"  to  use
              XA_PRIMARY  (default),  "secondary"  for  XA_SECONDARY or "clip‐
              board" for XA_CLIPBOARD
