How does Office 2008 for Mac store its Recent items?
At least on my machine, this is what I'm seeing:


PPT3 does appear to be the PowerPoint value
I have lots of items. MSWD0, MSWD1, but then also MSWD99, MSWD109, etc. 
Interestingly enough, it looks like PowerPoint adds items to Apple -&gt; Recent Items, but Word and Excel do not. Which seems crazy, but that's what's happening on my machine.
