Moving With Mouse

You can easily move the insertion point by clicking in your text anywhere on the screen. Sometime if the sheet is big then you cannot see a place where you want to move. In such situations, you would have to use the scroll bars, as shown in the following screen shot:

You can scroll your sheet by rolling your mouse wheel, which is equivalent to clicking the up-arrow or down-arrow buttons in the scroll bar.
Moving with Scroll Bars
As shown in the above screen capture, there are two scroll bars: one for moving vertically within the sheet, and one for moving horizontally.
Using the vertical scroll bar, you may:

Move upward by one line by clicking the upward-pointing scroll arrow.
Move downward by one line by clicking the downward-pointing scroll arrow.
Move one next page, using next page button (footnote).
Move one previous page, using previous page button (footnote).
Use Browse Object button to move through the sheet, going from one chosen object to the next.
