There are several ways to find what you are looking for in a code base.
Ctrl-Shift-M open module
Opens a dialog where you can start entering the name of the module you want to open. Usually a few characters are enough, select it from the list and press enter.
Ctrl-Shift-R open resource
Same thing, but works for any file (text, java, asn1, idl or whatever).
The Erlang search lets you search for functions/records/macros, as references, definitions or both.
Ctrl-Shift-G find references/definitions
Shortcuts for searching references and definitions for the element at the cursor, in the current editor.
Ctrl-click open definition
Go directly to the definition of the element at the cursor.
Ctrl-O quick outline
Opens a module outline where you can start typing to filter the elements you are interested in.
Ctrl-Shift-J text search
Textual search in the current file. The latter two perform incremental search for the current selected text or if none, for text being entered.
