Outliner 2023 doesn't recognise keystrokes

Just switched to Sketchup 2023 and I’m frustrated with the Outliner. It’s not responding to keystrokes like it used to. Can’t delete items with the delete key or use shortcuts to cut, copy or paste, which was very useful for moving items between nested groups and components. It also means you can’t use shortcuts to change tools, from Select to Move, from instance, when selecting items in the Outliner. Anyone else facing this issue? Any solutions?
