The print screen key does not open the screen shot tool in Kubuntu 16.10

Kubuntu 16.10 replaces the old screen shot tool KSnapshot with Spectacle but does not change the keyboard setting accordingly. Under System Settings -> Shortcuts -> Custom Shortcuts the folder “Screenshots” must be developed to show an entry “Start Screenshot Tool”. The trigger for this entry must be set to be the print screen key. A dialog will prompt warning that the key is already assigned; it is assigned to KSnapshot; therefore ignore the warning.
