 2.3 Movement
 ============
 
 ‘C-c C-b’
      Move to the beginning of the body of the message
      (‘message-goto-body’).
 
 ‘C-c C-i’
      Move to the signature of the message (‘message-goto-signature’).
 
 ‘C-a’
      If at beginning of header value, go to beginning of line, else go
      to beginning of header value.  (The header value comes after the
      header name and the colon.)  This behavior can be disabled by
      toggling the variable ‘message-beginning-of-line’.
