AutoIndent

AutoIndent
is an option for Style and Cell which specifies what automatic indentation should be done at the beginning of a new line after an explicit return character has been entered.

MORE INFORMATION

Possible settings for AutoIndent are:

	False	do no indentation
	True	indent the same as the previous line
	Automatic	indent according to the structure of the expression (default)

With AutoIndent->True, tabs or spaces used for indentation on the previous line are explicitly inserted at the beginning of the new line.

With AutoIndent->Automatic, line breaks are always indicated by an \[IndentingNewLine] character even if they were originally entered using ↵ or \[NewLine].

Indentation after an \[IndentingNewLine] is automatically redone every time an expression is displayed.

The amount of indentation after an \[IndentingNewLine] is determined by the settings for the LineIndent and LineIndentMaxFraction options.

Create a cell with AutoIndent->True:

In[1]:=

Type some spaces at the beginning of a line:

When you press the Enter key, Mathematica inserts the same indentation in the next line:

Create a cell with AutoIndent->Automatic:

In[1]:=

Every time you press Enter in this cell, Mathematica indents according to expression structure:

As you edit the cell further, the structural indentation shifts appropriately:
