Scrolling Within a Message
**************************

   When Rmail displays a message that does not fit on the screen, you
have to scroll through it.  You could use `C-v', `M-v', and `M-<', but
scrolling is so frequent in Rmail that it deserves to be easier to type.

`<SPC>'
     Scroll forward (`scroll-up').

`<DEL>'
     Scroll backward (`scroll-down').

`.'
     Scroll to start of message (`rmail-beginning-of-message').

   Since the most common thing to do while reading a message is to
scroll through it by screenfuls, Rmail makes <SPC> and <DEL> synonyms of
`C-v' (`scroll-up') and `M-v' (`scroll-down')

   The command `.' (`rmail-beginning-of-message') scrolls back to the
beginning of a selected message.  This is not quite the same as `M-<':
first, it does not set the mark; secondly, it resets the buffer
boundaries to the current message if you have changed them.
