9.1.3 Commands to Mark Textual Objects
There are commands for placing point and the mark around a textual
object such as a word, list, paragraph or page.
Set mark after end of next word (`mark-word'). This command and
the following one do not move point.
Set mark after end of next Lisp expression (`mark-sexp').
Put region around current paragraph (`mark-paragraph').
Put region around current Lisp defun (`mark-defun').
Put region around entire buffer (`mark-whole-buffer').
Put region around current page (`mark-page').
`M-@' (`mark-word') puts the mark at the end of the next word, while
`C-M-@' (`mark-sexp') puts it at the end of the next Lisp expression.
These characters sometimes save you some typing.
A number of commands are available that set both point and mark and
thus delimit an object in the buffer. `M-h' (`mark-paragraph') moves
point to the beginning of the paragraph that surrounds or follows
point, and puts the mark at the end of that paragraph (Note:
Paragraphs). You can then indent, case-convert, or kill the whole
paragraph. In the same fashion, `C-M-h' (`mark-defun') puts point
before and the mark after the current or following defun (Note:
Defuns). `C-x C-p' (`mark-page') puts point before the current page
(or the next or previous, depending on the argument), and mark at the
end (Note: Pages). The mark goes after the terminating page
delimiter (to include it), while point goes after the preceding page
delimiter (to exclude it). Finally, `C-x h' (`mark-whole-buffer') sets
up the entire buffer as the region by putting point at the beginning
and the mark at the end.
