2.2 Completion of Modules and Functions

Completion allows you to write some part of a module or remote function name and then press M-TAB to have it completed automatically. When multiple completions exist they are displayed in a popup buffer, much like Emacs's normal filename completion. The completion buffer can simply be read to see which completions exist, or either RET or the middle mouse button can be used to select one.

M-TAB

Complete the module or function at point. (erl-complete)

M-?

Alternative binding for erl-complete, since M-TAB is often reserved by window managers.
