I am not sure if this has been reported yet, as the term slur is rather broad when searching through the forum, but I have encountered an inconsistent behaviour, when slurs are selected together with notes and the alt+shift+arrow command is used.
Certainly this is something that won’t work the way you might be expecting, because reducing the duration of notes and slurs will increment by different amounts.
Thanks for your response Daniel.
This I am aware of. I don’t mind it, but I was surprised it didn’t move back the other way with shift+alt+right arrow, as both items were still selected.
