To scroll through the document
There are several ways of scrolling through the document:
If you use the PageDown key on your keyboard, EscapeE brings the next piece of text into view. Thus, if you are viewing a whole page, it will show the next page, but, if you are viewing only part of a page, it will show the rest of the page until it reaches the bottom of the page. After this it will go on to the top of the next page. This is useful if you are using 'View Page Width' scale.
If you use the Arrow keys on your keyboard, EscapeE scrolls the page incrementally.
Keying ctrl+n displays the next page; keying ctrl+b displays the previous page.
Select Next Page to display the following page.
Select Previous Page to display the preceding page.
There are buttons on the 'Field definitions' dialogue also:.
