Tabs and indents

Item	Description
Use tab character	If this check box is selected, tab characters are used: Otherwise, spaces are used instead of tabs.
Smart tabs	If this check box is selected, IntelliJ IDEA inserts tabs for indentation and reformatting, but fine alignment to a necessary column is done only via spaces. This is done in order to preserve visual representation of the source code, when the Tab Size is changed. If this check box is not selected, then spaces are used for alignment if necessary. This check box is available if the Use Tab Character check box is selected.
Tab size	In this text box, specify the number of spaces included in a tab.
Indent	In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted for each indent level.

Spaces

Use this tab to specify where you want spaces in your code. To have IntelliJ IDEA automatically insert a space at a location, select the check box next to this location in the list. The results are displayed in the Preview pane.

Wrapping and braces

In this tab, customize the code style options, which IntelliJ IDEA will apply on reformatting the source code. The left-hand pane contains the list of exceptions (Keep when reformatting), and placement and alignment options for the various code constructs (lists, statements, operations, annotations, etc.). The right-hand pane shows preview.

Keep when reformatting

Use the check boxes to configure exceptions that IntelliJ IDEA will make when reformatting the source code.

Blank lines

Use this tab to define where and how many blank lines you want IntelliJ IDEA to retain and insert in your code after reformatting. For each type of location, specify the number of blank lines to be inserted. The results are displayed in the Preview pane.

Item	Description
Keep Maximum Blank Lines	In this area, specify the number of blank lines to be kept after reformatting in the specified locations.
Minimum Blank Lines	In the text boxes in this area, specify the number of blank lines to be present in the specified locations. Warning These settings do not influence the number of blank lines before the first and after the last item.

Other

Item	Description
Indent package statement children	Select this check box to have the nested statements of package statements indented on code reformatting.
Align object properties	From the drop-down list, select the type of objects' alignment: Do not align: the attributes in sequential lines will be not aligned. On colon: the attributes in sequential lines will be aligned against the colon. On value: the attributes in sequential lines will be aligned against the value.
Field prefix	In this text box, specify the prefix to be used in ActionScript fields.
Property prefix	In this text box, specify the prefix to be used in ActionScript properties.
Use semicolon to terminate statements	Select this check box to have statements terminated with a semicolon.

Arrangement

Item	Description
Grouping Rules	Use this area to set the grouping rules.
Matching rules	Use this area to define elements order as a list of rules, where every rule has a set of matches such as modifier or type. - use this button to add a rule. The empty rule dialog window opens. - use this button to remove the rule from the list. - use this button to edit an existing rule. To see this button, navigate to the rule that you want to edit and click on the button. In pop-up window that opens, modify the rule fields. - use these buttons to move the selected rule up or down.
Empty rule	Use this window to create a new matching rule or edit an existing one. You can select from the following filters: Type - use this filter to choose classes or methods for your rule. Name - use this field to specify entry names in the rule. This filter matches only entry names such as field names, method names, class names and etc. The filter supports regular expressions and uses a standard syntax. The match is performed against the entire name. Order - use this option to select the sorting order for the rule. This option is useful when more than one element uses the same matching rule. In this case, selecting Keep order will keep the same order as was set before the rearrangement and selecting Order by Name will sort the elements with the same matching rule by their names.
	This icon appears when you select Order by Name in Order option. The icon indicates that the items in this rule are alphabetized.
