By default, Affinity Designer's Duplicate function keyboard shortcut assigned to Opt+Shift+Cmd+S.
Not very handy shortcut, you know. I used to Cmd+D.
So I went to the applications Preferences pane, to change keyboard shortcut to a custom one.
1. There was an attention sign near shortcut, which represented some kind if a conflict I suppose, but I failed to know what exactly.
2. Trying to reassign keyboard shortcut to a new one, I failed again, cause AD refused to save my changes. Whatever I did – plain assign, empty it's value in every persona dropdown, reload the application, it all went the same – no changes.
3. Lastly I force assign new shortcut in Keyboard Preferences of OS Preferences pane. And it helped, but I still observe same Opt+Shift+Cmd+S shortcut assigned to Duplicate function in apps preferences, despite in menu is has changed.
This is wrong. I suppose.
