It is and it isn't a cut and paste job.
With the screen you want to copy up and in full view you hit the print screen button on your keyboard. Then start Paint. You can paste the image into paint from the clipboard. You will neeed to crop the image to get to 640X640 or less. Save the image as a .Jpeg file. I then start up a graphic editing program like Microsoft photo and crop the image I saved from paint. and save it to a .Jpeg again. Then I write my post and use the insert image feature at the bottom of the post page.
Not a one step process but as they say a picture is worth a 1000 words!
