In the past I used to fire ksnapshot by hitting the Print Screen key on my keyboard.
Since some time now (< 1 year, I am running Kubuntu 14.04 with KDE v4.13.3) this is not happening anymore.
Moreover, in System Settings → Shortcuts and Gestures → Global keyboard shortcuts there seems to be no way to setup in kwin ksnapshot with the Print Screen key.
Any solution? Is this a bug?
