5.4 Priorities
If you use Org mode extensively, you may end up with enough TODO items that it starts to make sense to prioritize them. Prioritizing can be done by placing a priority cookie into the headline of a TODO item, like this
*** TODO [#A] Write letter to Sam Fortune
Org mode supports three priorities: 'A', 'B', and 'C'. 'A' is the
highest, 'B' the default if none is given. Priorities make
a difference only in the agenda.
C-c , (org-priority)
Set the priority of the current headline. Press A,
B or C to select a priority, or SPC
to remove the cookie.
S-UP (org-priority-up)
S-DOWN (org-priority-down)
Increase/decrease the priority of the current headline.
