For years i've used ClipTrak to manage the Windows Clipboard. It lets you recall up to 100 clips with the click of your mouse. But today i found that it is no longer available for download off the Internet, so i can't recommend it to others anymore.
After a little research today, i came across "Clipboard Magic".
Clipboard Magic is a Windows clipboard enhancement utility. It can dramatically enhance your productivity when cutting and pasting text or for filling in web forms. It apparently lets you store hundreds of clips in an unlimited number of "lists" which comes in very handy for categorizing various clips. And each clip can readily be placed back as the "active" clip by a click of the mouse. Look like it'll be a very handy tool.
It is FREEWARE and is available for download at:
