You can move an action area easily by dragging it or by using redraw mode. Be aware that double-clicking on the screen will resize the action area.
To move the action area by dragging:
Point to any area within the action area. The mouse pointer changes into a four-headed arrow.
Hold the left mouse button and drag the action area to any location and release the mouse button.
To move an action area using redraw mode:
Hold the CTRL key and click the left mouse button outside of the existing action area in the location where you want the upper left corner of the action area to appear. The mouse pointer changes into a crosshair and the upper left corner of the action area is positioned in the new location.
Drag to extend the action area over the area of the screen you want to reference.
Release the mouse button and the CTRL key where you want the lower right corner of the action area to appear.
