Error in manual
I'm using 2.0.2 on Mac.
I don't think the online manual has correct
instructions for cross staff beaming at
https://musescore.org/en/handbook/cross-staff-beaming-0
I have a macbook, and cmd+shift+down-arrow works, but not the indicated
cmd+shift+.
Comments
The manual shows ⌘+Shift+↓, so I don't get your issue
