Can no longer use Shift-Return for Line Break in Pages
Since upgrading to Sonoma, my keyboard shortcut for Line Break (menu: Insert: Line Break), which used to be ⇧-Return, isn't acceptable in the System Settings: Keyboard: Keyboard Shortcuts: App Shortcuts. It won't accept Shift as a possible function key. It accepts Shift-Command-Letter, but not Shift-Letter.
I've always had quite a few App Shortcut menu changes through Keyboard Shortcuts, so I'm quite familiar with the set up there.
Any ideas on how to assign just Shift-Return to the Line Break function?
