[Orgmode] Help with binding new key to change task state

[Varnit Suri]

Hi all,

The org manual talks about using C-u C-c C-t to change the state of a
task. This command nicely throws up a list of several intermediate
states to choose from. In addition, I have logging turned on, so each
time I do this, I can log a note about the state change.

I am merely trying to bind this to a simpler set of keys. I know C-c C-t
is bound to org-todo, but can't figure out what C-u C-c C-t binds to
(describe-key stops at C-u). Or then, maybe I don't know Emacs/Org well
enough yet. Any suggestions?

The second thing I am trying to do is have a shortcut to take a task
from TODO to DONE without going through the above process.

Thanks,

V.
