I migrated to Windows 11 and there is only one thing which is different:
I have customized F2 System-Wide "inline Rename". I see it in the Hotkey "(System-Wide)" section.
This did work in Windows 10 but no longer in Windows 11.
Have I overseen or fogortten something !?
Sorry for the silence. I deleted my hotkey change and everything is now working as expected. Don't know what I have done and why my F2-key was flagged as System-Wide.
