Screen Navigation
For more information refer to pages 60-61 in the text.
The size and position of the horizontal and vertical scroll boxes give you information about the size of the document and the position of insertion point on the screen you are viewing.
The size of the scroll boxes in relation to the length of the scroll bar is roughly proportional to the size of the document.
In this picture, the horizontal scroll box is quite long, meaning that you are viewing most of the width of the document. Additionally, the scroll box is in the middle of the scroll bar meaning that what you are seeing is in the middle of the width of the document.
The vertical scroll bar, however, is small and positioned near the top of the vertical scroll bar. Using the same principles, how much document is below the screen you are viewing?
If the horizontal scroll bar is missing this indicates that you are viewing the entire width of the file. When the vertical scroll bar is missing, the entire length of the file is visible in the screen.
Moving the Visisble Screen
There are two ways to move what you see on the screen. One moves almost a line at a time, the other moves much faster.
To move one line at a time, click the small arrowheads that you see at either end of the scroll bars.
To move faster, drag the scroll box.
The vertical scroll box is near the top and is small in relation to the length of the scroll bar. Thus, the information you are seeing is at the beginning of the document, and the document extends beyond what is seen on the screen. If the scroll box was in the middle of the scroll bar you would be half way down the document.
