In this area, choose the code style scheme and change it as required. Code style scheme settings are automatically applied every time IntelliJ IDEA generates, refactors, or reformats your code.
Code styles are defined at the project level and at the IDE level (global).
At the Project level, settings are grouped under the Project scheme, which is predefined and is marked in bold. The Project style scheme is applied to the current project only.
You can copy the Project scheme to the IDE level, using the Copy to IDE... command.
At the IDE level, settings are grouped under the predefined Default scheme (marked in bold), and any other scheme created by the user by the Duplicate command (marked as plain text). Global settings are used when the user doesn't want to keep code style settings with the project and share them.
You can copy the IDE scheme to the current project, using the Copy to Project... command.
From this drop-down list, select the scheme to be used. The predefined schemes are shown bold. The custom schemes, ones created as copies of the predefined schemes, are in plain text. The location where the scheme is stored is written next to each scheme, for example, the Default scheme is stored in the IDE, the Project scheme is stored in the project.
Click this button to invoke the drop-down list of commands to manage the schemes:

Text files and unsupported file types
Use tab character
If this check box is selected, tab characters are used:
On pressing the Tab key
For code reformatting
When the check box is cleared, IntelliJ IDEA uses spaces instead of tabs.
If this check box is selected, the part of indentation defined by the nesting of code blocks, is made of the tabs and (if necessary) spaces, while the part of indentation defined by the alignment is made only of spaces.
If this check box is cleared, only tabs are used. This means that a group of spaces that fits the specified tab size is automatically replaced with a tab, which may result in breaking fine alignment.
The Smart Tabs check box is available if the Use Tab Character check box is selected.
In this text box, specify the number of spaces included in a tab.
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.
