When I press PrtScr, a screenshot of the whole screen is placed on the Clipboard. And when I press Win+PrtScr it's placed in the screenshots folder. But when I press Alt+PrtScr - nothing happens ("nothing" includes that there is nothing on the clipboard which was mentioned above, of course). Not even a screenshot of the whole screen.
I've tried pressing Fn along with that combination, and Shift, and Ctrl, but to no avail.
Is there some Windows setting for disabling that that might have been set? Might there be an application listening to that keyboard shortcut? A registry setting for it?
Alt+PrnScr
will place the screenshot of the current window in clipboard. You need to paste to some app to get the screenshot
