There are a few ways to easily change the size and position of the Help Viewer and the panes in the viewer:
To resize the Navigation or Topic pane, point to the divider between the two panes. When the pointer changes to a double-headed arrow, drag the divider right or left.
To proportionately shrink or enlarge the whole Help Viewer, point to any corner of the Help Viewer. When the pointer changes to a double-headed arrow, drag the corner.
To change the height or width of the Help Viewer, point to the top, bottom, left, or right edge of the Help Viewer. When the pointer changes to a double-headed arrow, drag the edge.
To reposition the Help Viewer on your screen, click the title bar and drag the Viewer to a new position.
Note
The Help Viewer will appear with the last size and position settings you specified when it is opened again.
