You are looking at the Emacs tutorial.
Emacs commands generally involve the CONTROL key (sometimes labelled
CTRL or CTL) or the META key (sometimes labelled EDIT). Rather than
CTRL or CTL) or the META key (sometimes labelled EDIT or ALT). Rather than
write out META or CONTROL each time we want you to prefix a character,
we'll use the following abbreviations:
C-<chr> means hold the CONTROL key while typing the character <chr>
Thus, C-f would be: hold the CONTROL key and type f.
M-<chr> means hold the META or EDIT key down while typing <chr>.
If there is no META or EDIT key, type <ESC>, release it,
M-<chr> means hold the META or EDIT or ALT key down while typing <chr>.
If there is no META key or equivalent, type <ESC>, release it,
then type the character <chr>. "<ESC>" stands for the
key labelled "ESC".

C-M-v is an example of a CONTROL-META character. If you have a real
META key, you can type C-M-v by holding down both CTRL and META while
typing v.
It doesn't matter whether CTRL or META "comes first," because both of
these keys act by modifying the characters you type. But if you don't
have a real META key, and you use ESC instead, the order does matter:
you must type ESC followed by CTRL-v; CTRL-ESC v will not work. This
is because ESC is a character in its own right, not a modifier key.
