## Saving Positions in Registers

Saving a position records a place in a buffer so that you can move back there later. Moving to a saved position switches to that buffer and moves point to that place in it.

`C-x r `SPC` r`
  Save position of point in register r (`point-to-register`).
`C-x r j r`
  Jump to the position saved in register r (`jump-to-register`).

To save the current position of point in a register, choose a name r and type `C-x r `SPC` r`. The register r retains the position thus saved until you store something else in that register.

The command `C-x r j r` moves point to the position recorded in register r. The register is not affected; it continues to record the same position. You can jump to the saved position any number of times.

If you use `C-x r j` to go to a saved position, but the buffer it was saved from has been killed, `C-x r j` tries to create the buffer again by visiting the same file. Of course, this works only for buffers that were visiting files.
