Shift - Alt - D shortcut - Again

I asked this question a few days ago. I even got a reply in my email. But
when I click on the link in the reply, nothing happens. I am never actually
taken to the question and I am unable to refind the question here on this
forum. So, here goes again.

I have been using the Shift-Alt-D short cut lately and supposed it would put
in a date in my WORD document that is static. It does not. I discovered
subsequently that the day changes to whatever today's date is when you reopen
files. (like a day or two later)

Is there a shortcut key that will allow me to put today's date quickly in a
document and it not change subsequently?
