It appears that Greenshot hot-key combo's are configurable but all those key combo's work for me because my F13 invokes the PC's 'Prt-scrn' key After I installed Greenshot and went to do a screen cap I thought 'oh ! Because I don't have a 'print-screen' key and that's what lead me here. I downloaded Greenshot a couple days ago, so I've used it exactly 3 times so far and those 3 screen caps are uploaded here. Print Screen Section From Greenshot showing me writing this on the PC invoked from the Mac's F13 thru RDP I was unaware of Greenshot until a few days ago The PC belongs to my customer so I don't want to buy Snag-it for it. I needed this because I do A LOT of screen caps for work and the 'snipping tool' sucks rocks.

Greenshot's defaults are set to use the PC's print-screen key. Attached is the cmd-shift-4 screen cap of the RDP session showing 'Greenshot' just after it was invoked thru the RDP session via F13 from the Mac's wireless keyboard (I emailed the Mac screen cap to the work PC). I just found this forum cause I needed to do this and I just happened to try F13 after something I read here inspired me to do so.

I have an old bluetooth Model A1016 that looks just like the above keyboard sans cord and F13 invokes printscreen thru my RDP session on the Windows7 PC I'm controlling via my old Macbook Air 11
