Screen to Paper

I know that the world is moving towards digitization of content. But, I am still not ready to go with the flow! Here is what happened today - I had a small control-key references for an application on my desktop. Now, I want it to be on a physical post-it that I can paste next to my monitor. But, I don't want to go through the pain of writing the info manually! :)

How about having a 'sensitive' paper that I can just keep-pressed on the area that I need to copy from my desktop monitor!...this paper will copy the portion of the monitor onto itself auto-magically! No need to write things down anymore!
