Fire up emacs and type M-x tetris

if it was a valid command or if it had a suffix like '-mode'.
I played tetris for a couple of seconds, then closed the buffer with
I looked up help on tetris with C-h a, the 'apropos' command in the
help system, to which I typed 'tetris'.
I picked the tetris game from the buffer that showed the results of
apropos, and I got the help specific to tetris.
The help buffer included the fact that tetris is an interactive
compiled lisp function from the file 'tetris.el', and hyperlinked to
the source file itself. It also mentioned where it was bound in the
