What is the shortcut in IntelliJ IDEA to find method / functions?

Question

I know that Ctrl + N is to find classes and it is very useful. But what about methods?

Answer 1

I tried SHIFT + SHIFT and ALT + CMD + O

But I think the most powerful and easy to use feature is find in all files CMD + SHIFT + F.

Choose regex and write .*partOfMethodName.*\( and it shows all places and can see the actual source code in place without going to that specific file.
