Mark Commands
=============
The following commands are used to mark positions in the buffer.
`m CH'
Store current point in the register CH. CH must be a lower-case
ASCII letter.
`m <'
Set mark at the beginning of current buffer.
`m >'
Set mark at the end of current buffer.
`m .'
Set mark at point.
`m ,'
Jump to mark (and pop mark off the mark ring).
Emacs uses the "mark ring" to store marked positions. The commands
`m <', `m >' and `m .' not only set mark but also add it as the latest
element of the mark ring (replacing the oldest one). By repeating the
command ``m ,'' you can visit older and older marked positions. You
will eventually be in a loop as the mark ring is a ring.
