PureText
Copying and pasting text between applications can be troublesome (at least in a Windows environment), because copying text also copies the formatting rules along with it.
So, if I copy something from a website and paste it into Word, the text is often in a mismatching font, color, size etc. Word allows you to "Paste Special | Unformatted" but that is several clicks or mouseactions.
Usually I want just the text, formatted to match the destination.
