Function: reindent-then-newline-and-indent

reindent-then-newline-and-indent is an interactive and byte-compiled function defined in simple.el.gz.

Signature

(reindent-then-newline-and-indent)

Documentation

Reindent current line, insert newline, then indent the new line.

Indentation of both lines is done according to the current major mode, which means calling the current 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 indents to the column specified by the function current-left-margin.

Probably introduced at or before Emacs version 24.3.
