From Ace Clipboard:
The Ace Clipboard floats on top of your current work. Whenever you cut or copy, the clip appears in Ace. To paste back a clip, all you have to do is click on the one you want. The clips window only shows the first few words of each clip but when you move the mouse pointer over the window, a preview window appears showing the first several lines of a text clip or a thumbnail of a graphic clip. This makes choosing the clip you want to paste very easy. Ace is also an excellent screen capture program. To capture the entire screen, type Prt Scr. To capture just the active window, type Alt + Prt Scr. To capture graphics from Word or Internet Explorer, right click on the graphic and click copy. The graphics editor allows you to add text, and clip art as well as crop, re-size and rotate your screen shots. Unlike the standard Windows Clipboard, Ace allows you to paste graphic clips directly into Outlook and Windows Mail emails. You can even have it automatically reduce the size of photo clips as it pastes.
