Hi,

I don't know the requisite information to properly add a "secret," so  
I hope that someone with higher knowledge will read this and share it  
with the Secrets community.

I found the idea here:

"The new Spotlight feature in Tiger does a great job at searching the  
contents of PDF files. Clicking on the result will open the file in  
Preview, starting at the first reference. However, the default zoom is  
so large that the context containing the reference is lost without  
manually zooming out."

The default zoom factor is 28x.  Further down the page, someone else  
submitted the Terminal command:

defaults write com.apple.Preview Preview -dict-add  
PVPDFSpotlightSelectionSize 1

Now a PDF is opened at "fit to window" scale.  I hope this is  
helpful.  Thanks!

Yours,
Tim.
