C-h k TAB says the following:

TAB runs the command lisp-indent-line
   which is an interactive compiled Lisp function in 
`emacs-lisp/lisp-mode'.
(lisp-indent-line &optional WHOLE-EXP)

Indent current line as Lisp code.
With argument, indent any additional lines of the same expression
rigidly along with this one.
