[Orgmode] Emacs/Org-mode question

[Markus Heller]

Hello all,

this might be a typical beginner question ...

I often use the sequence

C-. <Ret> C-- :

to create this:

- <2009-07-31 Fri>:

where the date is today's date.

I'm sure there's a way to create a command for this, but I have no idea 
how.  I'd like to bind this sequence to something like C-c t or similar.

How do I do this?

Thanks and Cheers
Markus
