Klipper in Ubuntu-Gnome

One of KDE's handiest apps, Klipper, works on Ubuntu's gnome desktop!
If you've only worked in Gnome, you might be unaware of a little application called Klipper. It's KDE's answer to the traditional clipboard.
The wonderful integration between applications is one of KDE's strongest features.
Something really cool in KDE 4 is Klipper. It extends the clipboard's functionality by remembering and storing your clipping/copying history.
To put it simply, anytime you copy something to the clipboard, it's saved and becomes selectable for pasting over and over.
To install, open a Terminal and type: sudo apt-get install klipper

If the hard way is your way, from your desktop go to System>>Administration>>Synaptic Package Manager, enter klipper in the search-box, select install, then apply. ( I usually add klipper to my startup applications too – Here's a link to the Ubuntu-Wiki-How-To).

Klipper is configurable. You can set the limit of items stored, as well as a keyboard shortcut to the pop-up menu. The pop-up menu is keyboard accessible, which means you can navigate the list of clippings using the TAB key without taking your hands off the keyboard. - Totally Pro! - and a godsend for anyone doing repetitive cutting and pasting! You can also choose to have the Klipper pop-up menu open at your cursor position. In all, about 10 settings and behaviors are configurable to suit your personal preferences.

With the pop-up window open, you can filter the list by typing keywords from your clips – the list updates as you type – which is great if you've got a long list of stored items.
Features like this real-time filter and the refined interface make Klipper look and feel professional. KDE 4.x is a step ahead of Gnome when it comes to spit and polish. Their desktop really shines.

One of the settings changes the behavior of in such a way that simply highlighting an area is enough to save it to the clipboard. No right-clicking necessary. Clipboard-actions extend Klipper's functionality even further. Basically, clipboard-actions are shortcuts to other applications. For example, clipboard-actions can launch Firefox when a highlighting a URL, Evolution for email and Gedit for file-paths etc.
Having tried Klipper, I find it somewhat surprising that it isn't a default app for Ubuntu. Klipper does what the basic clipboard should. - Stylish and simple.

There is a similar application intended for gnome environments, Glipper, but it's not as refined or configurable as Klipper. One thing Glipper has going for it is a function called "snippets"; It's basically a way of storing strings, or snippets, of often used text so they are permanently available in the pop-up menu. – Hopefully the Klipper developers will pick up on the usefulness of this feature, (I find it so useful that I have Glipper installed alongside Klipper).
