I’ve been playing musicals for work lately so I’ve seen a lot of rit and rall for those dramatic moments.

Cues! The smaller notes that aren’t your part, but are there in case you don’t have that instrument in your group. Mostly because my high-school music substitute teacher, who must have been close to 80 (the regular guy had to have an operation, and he was a quick replacement), called them “fly shit”. Some of my fondest high school memories are of him telling us all to “play the fly shit”. Thanks Herb!
