[Orgmode] kechord to create another line beginning with an inactive timestamp?

[Rainer Stengele]

Many times I am writing a protocol which needs to have timestamped 
entries (see Skype or Yahoo Messenger chats) like:

...
- [2007-12-29 Sa 00:48] blah
- [2007-12-29 Sa 00:56] blub
...

For that I have to enter:

M-<Enter>
C-u C-c ! <Enter>

I would really like it having a key chord giving me the next line with 
the current incative time stamp! Maybe C-S-<Enter>?

What do you think?
