CLCL is a clipboard expander, ideal for anyone who spends a lot of time copy-pasting and is tired of going back and forth between windows.
What CLCL does in essence is keep a record of everything you copy, keeping it accessible from a paperclip icon in your system tray. This extended clipboard can also be accessed by pressing ALT+C, where your saved content will be automatically pasted when clicked.
CLCL has a great deal of options, in a tabbed interface. The most important options are in the history tab, where number of saved items can be set as well as turning saving on. CLCL can save anything you put in your clipboard, whether it's a file, text or image. It's also possible to run it from a USB stick.
CLCL is a useful little clipboard application that has the benefit of being tiny, as well having lots of configuration options so you can use it in your own way.
