Add & Delete Region
Add Region – Split Single Region into Two
A new region is added by splitting a selected region into two, horizontally or vertically. If a region is split horizontally, the resulting two regions are next to each other, horizontally. If a region, such as the one in the above screenshot, is split vertically, one of the regions will be over the other, vertically, as in the following screenshot.
Delete Region
To delete a region, click the region’s Edit Region drop-down menu, and select its Remove Region option.
