### 13.4 Saving Window Configurations in Registers

You can save the window configuration of the selected frame in a register, or even the configuration of all windows in all frames, and restore the configuration later. See Windows, for information about window configurations.

`C-x r w r`

  Save the state of the selected frame’s windows in register r (`window-configuration-to-register`).

`C-x r f r`

  Save the state of all frames, including all their windows, in register r (`frameset-to-register`).

Use `C-x r j r` to restore a window or frame configuration. This is the same command used to restore a cursor position. When you restore a frame configuration, any existing frames not included in the configuration become invisible. If you wish to delete these frames instead, use `C-u C-x r j r`.
