# Content/code assist

If activated from a valid line of code in an editor, this command opens a scrollable list of available code completions. Some tips for using code assist:

- If you select and then hover over a selected line in the content assist list, you can view Javadoc information for that line.
- You can use the mouse or the keyboard (Up Arrow, Down Arrow, Page Up, Page Down, Home, End, Enter) to navigate and select lines in the list.
- Clicking or pressing Enter on a selected line in the list inserts the selection into the editor.
- You can access specialized content assist features inside Javadoc comments.

Configure the behaviour of the content assist in the Java > Editor preference page (Code Assist tab).
