I have a question about
"History Improvements
• You can now use ⌃↑ and ⌃↓ to navigate Alfred's default result history at any time
• Note: these shortcuts will need to be disassociated from Mission Control's shortcuts to use them in Alfred"
I disassociated Mission Control. So ⌃↑ and ⌃↓ are free now. Do I then still have to activate this feature?
