|Case sensitive completion||From this drop-down list, select the degree to which you want IntelliJ IDEA to take into consideration
the case sensitivity when suggesting matches for code completion. The available options are:
|Autocomplete when only one choice||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.|
|Autocomplete common prefix||If this check box is selected, IntelliJ IDEA automatically completes the prefix of a name, if all
the matches in the lookup list have a common prefix. For example, consider the following entry in the
After pressing Ctrl+SpaceControl Space, the prefix is automatically completed to the strings that all the methods start with:
|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 the section Using Suggestion List for details.
|Show static members after instance qualifier||If this check box is selected, the lookup list shows both static and non-static class members after an instance qualifier. Otherwise, only non-static members are shown.|

So doing, the suggestion list appears after the specified delay, and shrinks as you type.
If the check box is not selected, IntelliJ IDEA will not suggest code completion automatically.
|Preselect the first suggestion||Choose the way IntelliJ IDEA treats the suggestion list in the code completion autopopup. The following options are available:
If the suggestion list has no focus, you can either place the focus to the desired element using the arrow keys, or select the first element with the TabTab.
If the suggestion list has the focus, you can select an element as usual, with the SpaceSpace, EnterEnter, or dot .

If this check box is not selected, use Ctrl+QControl J to show quick documentation for the element at caret (class, method or field).
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+QControl J
|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+PCommand P to show the parameter info.
