When you press Ctrl+Shift+R (Windows), it opens a panel similar to Goto Anything. You can then type the function, class or whatever and it will bring you right to it.
Also, when your cursor is on a word, and you press F12, it will bring you to the definition of the class or function. This also works with CSS classes and ID's from your HTML.
