I often need to scan on the fly an image (graph, photo, drawing) or text (magazine, meeting document) to insert them without a document I'm hitting (meeting notes while by example). For that, this mouse is ideal for even a document that simply passes through my hands: I move the mouse over the area that interests me, I copy to the clipboard (text or image according to the document type) and I stick in my text. If it's an image, it's over, if it is a text, I have only to format it according to my document.
