I know that Ctrl + N is to find classes and it is very useful. But what about methods?
Intellij v 13.1.4, OSX
The Open Symbol keyboard shortcut is command+shift+s
To Find the actions build in the IDEA(reindent, create new, ...) you can use
CRTL+SHIFT+A
then type indent for example and ENTER.
Command + Option + O
Opens up the Symbol lookup that you can jump to most of the methods/functions in your currently opened document.
IntelliJ IDEA Version 12.13 Ultimate Edition:
Macs: command + option + shift + N or on Menu -> Navigate > Symbol ...
ctrl + F12 (cmd + F12 on macOS) will show all members of the current class in a popup window and let you pick up one. It works exactly like the ctrl + o shortcut in eclipse, much faster than ctrl + alt + shift + n
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.
