Glipper

Glipper, http://glipper.sourceforge.net/, is a clipboard manager for GNOME.  Glipper helps manage cutting and pasting text between applications.  Glipper, the clipboard icon in the upper right hand corner of your GNOME panel, keeps track of the last twenty items that have been cut or copied. 

To use Glipper, cut or copy your text by highlighting it, right clicking on and choo se copy (or use control-C).  To paste the last thing that was copied, right click your mouse and hit paste (or use control-V).  To choose to paste something other than than the last item copied, click on the Glipper icon, and click on the item to be pasted (screenshot below).  The most recent item copied to Glipper is on the top, with recent history going from top to bottom.  Once chosen, right click on your mouse and hit paste (or control v).

Glipper makes it easy to store items and quickly paste them from one application to another.
