AutoIndent

AutoIndent
is an option for Style and Cell that specifies what automatic indentation should be done at the beginning of a new line after an explicit return character has been entered.
MORE INFORMATION
Falsedo no indentation
Trueindent the same as the previous line
Automaticindent 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.
  • Indentation after an \[IndentingNewLine] is automatically redone every time an expression is displayed.
EXAMPLESCLOSE ALL
Basic Examples   (2)
Create a cell with AutoIndent->True:
Type some spaces at the beginning of a line:
When you press the
DynamicBox[ToBoxes[If[$OperatingSystem === MacOSX, Return, Enter], StandardForm], ImageSizeCache -> {35., {0., 9.}}]
key, Mathematica inserts the same indentation in the next line:
Create a cell with AutoIndent->Automatic:
Every time you press
DynamicBox[ToBoxes[If[$OperatingSystem === MacOSX, Return, Enter], StandardForm], ImageSizeCache -> {35., {0., 9.}}]
in this cell, Mathematica indents according to expression structure:
As you edit the cell further, the structural indentation shifts appropriately:
