|Auto-insert when only one choice on:
|When the check boxes in this section are selected, IntelliJ IDEA doesn't show a lookup list for the corresponding completion type in cases when only one variant of code completion is available, and completes code automatically.
|Sort lookup items lexicographically
|If this check box is selected, the entries in the suggestion list will be sorted according to their lexical order.
If this check box is not selected, the entries in the suggestion list will be sorted by relevance.
Note that the check box defines the default behavior. You can change it any time by clicking the or icons in the suggestion list. Refer to section Auto-Completing Code for details.

| Autopopup documentation (ms)
For explicitly invoked completion
| Select this check box to have IntelliJ IDEA automatically show a pop-up window with the documentation for the class, method, or field currently highlighted in the lookup list.

If this check box is not selected, use Ctrl+Q to show quick documentation for the element at caret.
Quick documentation window will automatically pop up with the specified delay in those cases only, when code completion has been invoked explicitly. For the automatic code completion list, documentation window will only show up on pressing Ctrl+Q
|Autopopup in (ms)
|Select this check box to have IntelliJ IDEA automatically show a pop-up window with all available method signatures, when an opening bracket is typed in the editor, or a method is selected from the lookup list.
In the text field to the right, specify the delay (in milliseconds) after when the pop-up window should appear.
If this check box is not selected, use Ctrl+P to show the parameter info.
