I was reading about the ‘Snipping Tool’ which is available as part of the Tablet PC tools in Vista. However there doesn’t appear to be a way to get this on Windows Server 2008.
Happily, and rather surprisingly there actuall IS a use for OneNote which is part of Office 2007. Simple do WindowsKey+S and you can cut-out a section of the screen which will promptly go in to OneNote from where you can then copy+paste it elsewhere. Admittedly not as slick as the Vista tool but useful none the less.
