Emacs commands editing the buffer contents are not available; instead, a
special set of commands (mostly letters and punctuation) are defined for
moving around in the buffer.
Space scrolls forward, Delete scrolls backward.
For a list of all View commands, type H or h while viewing.
This command runs the normal hook `view-mode-hook'.
