(defun set-mark-command (arg)
"Set mark at where point is, or jump to mark.
With no prefix argument, set mark, push old mark position on local mark
ring, and push mark on global mark ring. Immediately repeating the
command activates `transient-mark-mode' temporarily.
With no prefix argument, set mark, and push old mark position on local
mark ring; also push mark on global mark ring if last mark was set in
another buffer. Immediately repeating the command activates
`transient-mark-mode' temporarily.
With argument, jump to mark, and pop a new position for mark off the ring
\(does not affect global mark ring\). Repeating the command without
an argument jumps to the next position off the mark ring.
With argument, e.g. \\[universal-argument] \\[set-mark-command], \
jump to mark, and pop a new position
for mark off the local mark ring \(this does not affect the global
mark ring\). Use \\[pop-global-mark] to jump to a mark off the global
mark ring \(see `pop-global-mark'\).
Repeating the \\[set-mark-command] command without the prefix jumps to the next
position off the local (or global) mark ring.
With a double \\[universal-argument] prefix argument, e.g. \\[universal-argument] \

set mark where point is.
Novice Emacs Lisp programmers often try to use the mark for the wrong
purposes. See the documentation of `set-mark' for more information."
