Here is the feedback that I sent to apple:
I really love the baked-in "Save to PDF" function that OS 10 has. I love it so much, that I often have multiple things that I want to save as PDF. It is a little inconvenient/inefficient to go through five or six pages, hit cmd-p, click "PDF", select "Save as PDF", hit return, hit return again, for each file. It would be much easier if I could punch in one key combo and have the "Save" dialog box come up, with "PDF" in the format. Please help.
Thank you, and keep up the good work.

Does anyone know a trick that would accomplish this for me? Can Quicksilver do this?
Any advice is appreciated
