View FILE in View mode in another window.
When done, return that window to its previous buffer, and kill the
buffer visiting FILE if unmodified and if it wasn't visited before.
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'.
