###### To enable or disable the use of tab characters when indenting

- Select the Properties Window.

The editor can provide assistance with source code indentation while inserting text. There are three levels of indentation assistance:

- None. The indentation of the source code is left to the user.
- Indent (default). The editor maintains the current indentation level. When Return or Enter are pressed the editor automatically moves the cursor to the indentation level of the previous line.
- Smart. The editor analyses the source code to compute the appropriate indentation level for the line. The number of lines before the current cursor position that are analysed for context can be altered. The smart indent mode can be configured to either indent open and closing braces or the lines following the braces.
