Hippie Code Completion in IntelliJ IDEA?

Question

In NetBeans, it's Ctrl+K that activate the hippie completion.

In Eclipse, it's Alt+/.

What is it in IDEA?

Edit: Hippie Completion is the kind of completion that doesn't require much information about the context. It scans all the word in file(s) and immediately choose the first match. It originate in some variation of Emacs.

(a) You omitted a macOS shortcut. (b) And no, IntellliJ does indeed call it *Hippie completion*, at least nowadays. See [documentation](https://www.jetbrains.com/help/idea/auto-completing-code.html#hippie_completion). – Basil Bourque Oct 27 '22 at 22:14

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.

Hippie completion in IntelliJ

See the documentation. To quote:

Hippie completion is a completion engine that analyses your text in the visible scope and generates suggestions from the current context. It helps you complete any word from any of the currently opened files.

When using that documentation page, notice that the page is set to show keyboard shortcuts for one particular platform. To switch platforms, use the Shortcuts pop-up menu in the bar at upper-right corner of the window.

macOS

Press ⌥ / or choose Code | Code Completion | Cyclic Expand Word to search for matching words before the caret.
Press ⌥ ⇧ / or choose Code | Code Completion | Cyclic Expand Word (Backward) to search for matching words after the caret and in other open files.

Windows OS

Press Alt+/ or choose Code | Code Completion | Cyclic Expand Word to search for matching words before the caret.
Press Alt+Shift+/ or choose Code | Code Completion | Cyclic Expand Word (Backward) to search for matching words after the caret and in other open files.
