Changing the position and the width of the Control Panel
When the Control Panel is opened up, you can move it to other locations within Microsoft Word. By clicking and holding on the title bar, you can move the Control Panel to the top, left, right, or bottom of Microsoft Word. You can also change the width of the Control Panel by using the left column of the Control Panel for Fields and Clauses tabs.
When you expand the Control Panel, the leftmost column also moves with the cursor. In cases where you decrease the size of the Control Panel to a greater extent, use the scroll bar to view the various columns. Even tooltips for each record in the fields tab help you view the previous and current value of each record.
