AltGr + PrintScr
Because I need to write some manuals, I was looking for a good Screenshot-Utility for - I’m afraid to say it - Windows XP.
On Mac OS X you can just hit Command+Shift+4 and get a small crosshair to mark the area you want to copy.
And on Windowy you just hit AltGr + PrintScr and you’ll find the frontmost window in your clipboard, nice
Some better tools available that will also save the content in a .png-file? Still looking…
