What does C-h k RET say?

RET runs the command newline-and-indent
   which is an interactive compiled Lisp function in `simple'.
(newline-and-indent)

Insert a newline, then indent according to major mode.
Indentation is done using the value of `indent-line-function'.
In programming language modes, this is the same as TAB.
In some text modes, where TAB inserts a tab, this command indents to the
column specified by the function `current-left-margin'.
