By default, Org mode supports three priorities: =A=, =B=, and =C=.
=A= is the highest priority. An entry without a cookie is treated as
equivalent if it had priority =B=. Priorities make a difference only
for sorting in the agenda (see [[*Weekly/daily agenda]]); outside the
for sorting in the agenda (see [[*Weekly/daily agenda]]). Outside the

displayed with the face defined by the variable ~org-priority-faces~,
which can be customized.
You can also use numeric values for priorities, such as
: *** TODO [#1] Write letter to Sam Fortune
When using numeric priorities, you need to set ~org-priority-highest~,
~org-priority-lowest~ and ~org-priority-default~ to integers, which
must all be strictly inferior to 65.
Priorities can be attached to any outline node; they do not need to be
TODO items.
