Shortcut to search for elements in MuseScore.

Hello everybody!

There is a shortcut in MuseScore to quickly search for elements such as a measure number, for example. Therefore, I don't remember this shortcut, any tips or information would be very welcome!

Can any friend give me a link where I can find percussion and drum instruments so I can add them to my MuseScore 3.6.2?

Thanks friends!
