I use OneNote nearly every day and just upgraded to the (free!) 2013 version. This version registers both the Windows+S and Windows+Shift+S keyboard combinations. Unfortunately, this conflicts with a custom internal application that registers (and requires)Windows+Shift+S. I have found some instructions for changing the Windows+S hotkey, but nothing for the Windows+Shift+S hotkey combination. Is there any way to disable the conflicting shortcut in OneNote?
I discovered that changing the registry entry mentioned in the linked answer also changes the key for the Windows+Shift+S hotkey. That is, changing the "ScreenClippingShortcutKey" value to "5A" changes the mappings to Windows+Z and Windows+Shift+Z. Lucky for me!
