specifically: how to do "p-f" dynamics (first time, second time); generally: how to find this in the manuals

[Kenneth Wolcott]

Hi;

  Regarding the old fable: "Give me a fish, I can eat for a meal; Give
me a fishing pole, I can eat for a lifetime."...

I can't remember how to do dynamics pertaining to an implied repeat.

The music has "p -f" for dynamic marking.

The general problem: How do I search (what phrases should I use) to
find this information in the manual?

Thanks,
Ken Wolcott
