20.4 Paragraphs
===============

The Emacs commands for manipulating paragraphs are also `Meta-' keys.

`M-{'
     Move back to previous paragraph beginning
     (`backward-paragraph').

`M-}'
     Move forward to next paragraph end (`forward-paragraph').

`M-h'
     Put point and mark around this or next paragraph
     (`mark-paragraph').

   `Meta-{' moves to the beginning of the current or previous paragraph,
while `Meta-}' moves to the end of the current or next paragraph.
Blank lines and text formatter command lines separate paragraphs and are
not part of any paragraph.  An indented line starts a new paragraph.

   In major modes for programs (as opposed to Text mode), paragraphs
begin and end only at blank lines.  As a result, the paragraph commands
continue to be useful even though there are no paragraphs per se.

   When there is a fill prefix, paragraphs are delimited by all lines
which don't start with the fill prefix.  Note: Filling.

   To operate on a paragraph, you can use the command `Meta-h'
(`mark-paragraph') to set the region around it.  This command puts
point at the beginning and mark at the end of the paragraph point was
in.  If point is between paragraphs (in a run of blank lines or at a
boundary), the paragraph following point is surrounded by point and
mark.  If there are blank lines preceding the first line of the
paragraph, one of the blank lines is included in the region.  Thus, for
example, `M-h C-w' kills the paragraph around or after point.

   The precise definition of a paragraph boundary is controlled by the
variables `paragraph-separate' and `paragraph-start'.  The value of
`paragraph-start' is a regexp that matches any line that either starts
or separates paragraphs.  The value of `paragraph-separate' is another
regexp that  matches only lines that separate paragraphs without being
part of any paragraph.  Lines that start a new paragraph and are
contained in it must match both regexps.  For example, normally
`paragraph-start' is `"^[ \t\n\f]"' and `paragraph-separate' is `"^[
\t\f]*$"'.

   Normally it is desirable for page boundaries to separate paragraphs.
The default values of these variables recognize the usual separator for
pages.
