I happened to read http://linuxtoday.com/news_story.php3?ltsn=2004-02-24-023-26-OP-CY-DV-0100 wherein it was said that accesskeys for previous or next is as follows:
1. Mozilla/Netscape: Ctrl+Alt+P or Ctrl+Alt+N
2. IE: Alt+P or Alt+N, then press RETURN
But I always prefer using, ALT + right arrow for moving to the next screen and ALT + left arrow for moving to the previous screen in IE
I write about things which I am passionate about.
