Hippie Code Completion in IntelliJ IDEA?

The shortcut ⌥+/ stopped working on recent Macbooks.

You can change the shortcut, for example to Ctrl+/ and Ctrl+⌥+/, in your perferences. The feature is called Cyclic Expand Word in IntelliJ 14.

I have found it: Alt+/ or Alt+Shift+/. IDEA call it Expand word.
