I use software that displays the work environment on my main monitor (which is one application window) and a presentation display on my second monitor (which is a second application window).  With the presentation display on the second monitor activated, I can start typing the ID of an image I want to display with the text I am typing displayed in the bottom right corner of the presentation display.

Is it possible to create an application that would allow me to mirror just the bottom right corner of my presentation display in a small window on my main display so that I would not have to look at the second monitor to see what I am typing?  I cannot tell you how helpful such an application would be in my daily work.  Thanks!
