When writing articles or doing any text processing it often helps to use copy and paste. Not to steal texts, but copying long URLs, complicated names or just to refer to something.
And when you have copied something once to the clipboard it would be nice to get it back later on or to use it more often and not to have searching it again in written texts before.
Jumpcut
The helper tools for managing that kind of task is called a clipboard manager. There are plenty of them available, but most are quite expensive.
I found a simple and nice one which keeps only text in mind and not images, what I do really prefer. That program is named Jumpcut and freeware.
In the menu bar is a small scissors and clicking on it shows all previous cuts. Just select one to paste it back anywhere in a textbox. Even with a specialized and customizable shortcut you can scroll through them with a head up display.
