In the NR, most such functions have its argument starting with `#`, for example ``` \ottava #-2 ``` Are there still cases where `#` is mandatory for numbers? Otherwise the documentation could be updated to remove all `#`. BTW, I tried to look up details on `#`, and I see that neither the Notation Reference nor the Learning Manual has a proper explanation how to use the hash sign with respect to numbers. I faintly remember (not sure that I'm right) that David K. has worked on making it possible to use numbers without `#` as music function arguments, but I can't find a NEWS entry for that. Werner
