Herb:
<div>I don't know what is going on, but now, after quitting some applications and then coming back into TS and setting the Preview display to full screen (via the toolbar--the default is 120% magnification) I am able to use the up/down keys again.
<div>Problem solved (for now). Go figure.</div>
<div>Thanks for the advice.<br>

I am working on a book-length project, and using full screen (on the TexShop editor and preview) for the pdf output, in a 2-page display. I have gotten used to using the up/down keys to advance within the Preview, but recently, this is not working--when I
hit the down key I get a bell and no advance. Of course I can move the cursor to the top of the screen and, if I am agile enough, get the toolbar, where I can advance/go back to either the immediate next/previous page or toe the next/previous page selected
by my viewing history. But once I move to the new page, I have to work again to get the toolbar.
<div><br>
</div>
<div>So my question is, what controls whether I can use the up/down keys on my keyboard to advance or move back one pair of pages when in full screen/two-page format in preview?</div>
