how to shrink Docs-To-Go doc size on iPhone

Hi there,
I'm using Documents-To-Go... very nice. But the document that's the right size on my desktop, is too big on my iPhone. I can't seem to shrink it on the iPhone (with the finger-pinch motion), and I can't figure out if there's another way.
Can anyone tell me how to make this doc smaller on the iPhone?
Thanks, malch

 

Got it... it's on the second page of the Docs-to-Go prefs (at the bottom of the iPhone display)...
