We publish a semi-annual newsletter using Adobe InDesign CS5 (Mac) for our membership. We want to begin electronic distribution via email. This would be done via a link within an email that links them to the pdf of the newsletter on our website.
The problem is once the pdf appears, the reader must scroll vertically to read it. Is there a way to produce the pdf so that the reader can browse from page to page, similar to a book, horizontally, as opposed to vertical scrolling?
That is really a question you should ask in the InDesign forum.
However, I wonder why you would want to do that? My computer only has PageUp and PageDown keys, no PageRight or PageLeft. Or are you planning your newsletter for smartphones only?
