Short Cut of The Day: Take A Picture of an open window

Do you ever take a picture of the window you are using to send to someone? Have you ever wanted to put a picture of something you are working on on the web. I know i have. You could use the cross hair method by hitting Command – Shift – 4. But you have to draw it out just right. If you had one key to that combination then you could just select an open window and click and the snapshot shows up on the desktop as a .png. Use the Short cut Command – Shift – Space bar – 4 and the Camera icon shows up. Place it on the open window you want the snapshot of and click. It does not even have to be the top window.
