Sheesh, it was just a suggestion. Having worked in several usability labs with graphics professionals, what one might be inclined to think takes 15 seconds in reality takes a few minutes to do correctly (with the precision of an automated screen capture utility). You need to account for unpredictable variables like the extra time needed to stop what you are doing, shift to right-brain mode, familiarize yourself with the UI of the program you are using (unless you use Paintbrush every day, this takes at least 30-60 seconds), precision mousing is also time consuming -- it can take 15 seconds just to get one edge of the crop boundary where you need it.
What would take 15 seconds would be looking up and pressing the hotkey, then opening up the output directory to look at the resulting image.
Sometimes I can't help but wonder whether there is any point in posting here at all.
