C-u is the universal argument command. You need to find out what happens when the universal argument is given to C-space: C-h k C-space C-SPC runs the command set-mark-command which is an interactive compiled Lisp function in `simple'. (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. With argument, jump to mark, and pop a new position for mark off the ring (does not affect global mark ring). The last line tells you what C-SPC does 'with argument', which means when you prefix it with C-u. HTH, Tyler
