2.6 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.
