How to unset keyboard layout shortcuts in fedora

Yesterday I installed fedora. The set up allowed me to pick from a limited amount of shortcuts to switch the layout. Now, in KDE, I found that I can set the shortcut to switch layouts from the system settings, under keyboard layout, so I set my preferred shortcut there. Problem is, I can't figure out how to clear the shortcut I set during set-up. It's nowhere to be found. How do I unset the shortcut I specified during set-up?
