There are a number of programs called "Clipboard Extenders" which are designed to not only show you what is on the clipboard at any moment, but also to save some specified number & types of clipboard items that you may need.

There are MANY of these prograMS....these are the free ones (scroll down to 'clipboard extenders')....but two of them are rated especially well...ClCl & Yankee Clipper (YC3)

There are also several pay programs...particularly ClipMate....which is beyond amazing in what it can do...but is also formidable to learn.

I have a couple of the free programs ...one of which is always running- just in case....and one I open only when I need to save and organize...and possibly edit... a bunch of complex 'clips' for some project...and have them handy to paste into an application
