Jump Bar mode - Key Commands?

Dorico
1

Hello, somehow I can’t change my Jump Bar mode with a keyboard shortcut any more.
Dorico V. 4.3.31 in English, macOS 10.14.6, keyboard language German.
I deleted the suggested (and not working) Shift Cmd-1 for Command mode and Shift-Cmd-2 for Go To mode. I tried to set up new short keys. None are working, why could this be? Am I using wrong combinations?
What would be a good
-suggestion for Command Mode?
-suggestion for Go To Mode?

I have a feeling these two commands might not actually work in Dorico 4, but they do in Dorico 5.
