From M8 Software:
M8 Free Multi Clipboard is the simplest of all multi-clipboard programs. Just have it running minimized and it captures everything you cut or copy from other programs. It keeps up to 500 clips. When you want to paste one back, all you have to do is restore M8 and click on the clip you want. If you prefer to work entirely from the keyboard, you can choose a function key to restore M8 and then paste any clip by typing the letter shown next to it. When you move the mouse over the clips, you can see them in the viewer. If the clip is text, you see several lines and if it is a graphic, you see a thumbnail.
What's new in this version:
Version 17.0 has has added search and replace to the text editor, extended context menu, and the text manipulation functions which previously were applied to the entire clip, are now applied to selected text.
