For the orchestral score I am trying to work on, I am trying to input a whole cue line, however, the instructions given are not working. I have tried that whole Shift + U thing, and it does not work. All it gives me is a sign post that says “Violin II” and it does not show the cue notes. How can I get it to show?
Well, I guess you have to tick the right option in Layout options, with the Full score selected on the left panel…
Search Players>Cues>Show Cues 
It’s the default behavior, because usually, cues are for parts, since the full score shows… everything !
Elwin, in the full score, by default, cues show in galley view but not in page view.
