Invoke AI-powered code completion

Cloud completion powered by AI Assistant can autocomplete single lines, blocks of code, and even entire functions in real time based on the project context. The generated code is similar to how you would write code, matching your style and naming conventions.

Work with cloud completion in the editor

The suggestions are shown in the editor as you type.
You can also trigger the code completion by pressing Alt+Shift+\.
If there are no suggestions, the code might already be complete.
To apply the suggestion:
- Press Tab to accept the entire suggestion. You can configure a different shortcut for this action.
- Press Ctrl+Right to accept a suggestion word by word.
- Press End to accept a suggestion line by line.
To reject the suggestion, press Escape. Alternatively, just continue to write your own code or change the caret position either with the arrow keys or by a mouse click.

Configure cloud completion

The cloud completion option is enabled by default. You can configure the way it works in the settings.

Press Ctrl+Alt+S to open settings and select Editor | General | Inline Completion.
Available options to configure:

- Clear the Enable multi-line suggestions checkbox to leave only single-line suggestions.
- To disable this option completely, clear the Enable cloud completion suggestions checkbox on the same settings page or in Settings | Tools | AI Assistant.

Change the cloud completion shortcut

You can change the default cloud completion shortcut that you use to accept suggestions.

Hover over the suggestion.
In the popup that appears, click and select the key that you want to use for accepting suggestions, for example, Right.
To assign your own shortcut, select Custom.
