The Scroll Bar in Microsoft Office Word

Scroll bars, like in any other program windows, help in viewing a document that takes up more space than the document window view area. This may happen if document has more than one page or the zoom size for viewing large enough. The single up and down arrow in the vertical scroll bar make the document scroll one line in the direction of the arrow as they are clicked with the mouse. The box within the scroll bar indicates the position of the insertion point to the top of the previous page, and the down one move it to the top of the next page. The icon

in the middle of the double-headed arrows is the 'Select Browser Object' Option Button. It gives you different options to place the insertion point according to the browse setting you choose. These include browse by page ( this selection is by default) , end note, footnote, section, table, graphic, headings, etc.
