Ardour 7 keyboard shortcut

Manjaro Kde. Ardour 7.0.0 “More Blank Than Frank” (rev 7.0) Intel 64-bit

I want Shift+Alt+Left/Right to move the playhead to the next / previous region boundary, regardless of which track is active. I achieved this in Ardour 6.9, but in 7.0 it seems these keyboard shortcuts just sends the playhead to session start.

(I opened the Keyboard shortcuts dialog and changed ALT+Shift+Left to Move playhead to previous region boundary (no track selection)
