I've been researching for a day or two but can't find a method to take a screenshot of a specific window (possibly the only window) open at a specific time using an Apple script.
Currently I have the script execute:
screencapture -T1 ~/Desktop/screenshot.png
But what I want is really:
screencapture -wx -T1 ~/Desktop/screenshot.png
But when I use -wx, it waits for a mouse click on the window.
Are there any utilities, built in or not, that will allow me to do this?
Edit: The windows alternative that I'm looking for on a Mac is the keyboard shortcut:
Alt+PrntScrn
