Move a pane in the window by grabbing its title bar to show the “virtual rectangle” for the pane. The virtual rectangle is a dotted color frame that you can drag to the position in the window at which you want the pane to appear. When you are satisfied with the new position, release the mouse button. The other panes in the window are adjusted as necessary.
To swap the positions of the panes on either side of a splitter, select the splitter and choose Swap in the right-click menu. To change the color of the splitter when it is selected (and of its virtual rectangle), select the splitter and choose Color in the right-click menu. Use the standard Windows color control to specify the color.
