Changing default screen capture prog

Wondering how to change the default screen capture program (ksnapshot) to something else? (eg Shutter)
Have looked in the key bindong config etc, but can’t find anything…

Configure Desktop->Shortcuts and Gestures->Custom Shortcuts.
Select the “PrintScreen” input action (in the “Preset Actions” group) and switch to the “Action” tab. You can then change the command to run in the “Command/URL” field.
