The vertical scrolling in 2) can be enabled in Full Screen Mode by:
1. Go Full Screen in Adobe Reader [cmd + L]
2. Turn Automatic Scrolling on [cmd + shift + H]
3. Turn Automatic Scrolling off [cmd + shift + H again]
4. Now you can use your mouse/Up & Down arrow keys/trackpad to vertically scroll through your PDF
(however the mentioned black dashed lines appear and that's annoying)
I should say that PDF files are inherently a collection of pages, and it would never occur to Adobe to try to present it in any other way. You can make a single long page up to 200 inches in length.
Hi Test Screen Name,
Thanks a lot for your reply. It seems that PDFs are also meant to be for presentations. You can make them interactive and add videos, etc. For things like magazines, journals it would be useful to have a horiztonal scroll to emulate the experience of flicking through pages, rather than the vertical scroll.
It's actually a good idea to expand the pages in InDesign - this way there are no dashed black lines when scrolling.
A long page (or even a wide page) can be good for presentations but remember
- users doing their own navigation are likely to find themselves a bit lost - and their normal habits (like "fit whole page on screen" or "keyboard shortcut to move down a page") will let them down
- it's a nightmare for printing.
- to consider what it will do in the many other widespread PDF viewers (e.g. Chrome, Safari, Preview, FireFox, Windows 8 Reader...)
It's imporant to remember that your intended purpose of the PDF isn't always the user's intended purpose, and consider whether you want to make things harder for them. Sometimes it may be just what you want, sometimes not.
