GNU Emacs Manual - Help Mode

Go to the first, previous, next, last section, table of contents.

## Help Mode Commands

Help buffers provide the commands of View mode (see section Miscellaneous File Operations), plus a few special commands of their own.

``SPC``
  Scroll forward.
``DEL``
  Scroll backward.
``RET``
  Follow a cross reference at point.
``TAB``
  Move point forward to the next cross reference.
`S-`TAB``
  Move point back to the previous cross reference.
`Mouse-2`
  Follow a cross reference that you click on.

When a command name (see section Running Commands by Name) or variable name (see section Variables) appears in the documentation, it normally appears inside paired single-quotes. You can click on the name with `Mouse-2`, or move point there and type `RET`, to view the documentation of that command or variable. Use `C-c C-b` to retrace your steps.

There are convenient commands for moving point to cross references in the help text. `TAB` (`help-next-ref`) moves point down to the next cross reference. Use `S-`TAB`` to move point up to the previous cross reference (`help-previous-ref`).
