Can anyone post a lesson on how to do a screenshot for future refrence please.
This is how I do it. You can copy your screen by pressing CTRL and Print Screen (can be PRTSC or similar on the key - top right, normally after the F1 to F12 keys) together - that copies the screen you are looking at, then you can paste it into a photo viewing/editing program (whatever opens your photos for you).
When you press Prt Scr you don.t see anything until you have copied and pasted into a photo viewing program.
