Editor: Clyppan is a free and Open Source clipboard History application for Mac OS X that’s always at your Fingertips. It keeps a list of text you have copied to the clipboard and allows you to paste it again by selecting it from the list within Clyppan.
Features
Always at your fingertips: all of Clyppan’s functionality can be reach via the keyboard. Clyppan is designed so that you never need to reach for the mouse — unless you want to.
Rapid Paste: use Rapid Paste keyboard shortcut to put the next item in Clyppan’s list on to the clipboard. This is a great way of pasting multiple items without switching away from the application you’re working in.
Quick Preview: Get a better look at what you’ve copied. The Quick Preview feature allows you to view the whole text, not just the first line. Simply select a clipping from the list and hit Spacebar to bring Up the Quick Preview window.
Automatic updates: no Mac application is complete without being able to update itself, and Clyppan is no exception. By using the excellent Sparkle framework, bug fixes and new features will be delivered to you — automatically — as soon as they are available.
