With this function all extents stored in the project can be displayed as graphics in the view (black rectangle with the name of the extent in the left bottom corner) in order to give you an overview of the stored extents. Only those extents that overlap with the view are displayed. If you press the Shift key while activating the function, all extents of the project are displayed.
These named extents can be edited like all other graphics of ArcView (see below). When calling this function again, these graphics are removed from the view and are synchronized with the stored extents (changes you made to the graphics will be applied to the extents).
The graphics can be edited in ArcView as follows:
Hint: If you have made changes to graphics by mistake, then just delete them, but don't select them for deletion at synchronization. If you delete all graphics, all extents will be redrawn and not synchronized when calling the function again.
Hint: If you want to move the extent afterwards, you should also move the text, because it isn't grouped with the rectangle any more and would stay at its old position. This is not a problem when synchronizing the extents (the corresponding rectangle and text can be identified by their old names that are stored internally), but may create confusion at further editing. To avoid this, it is recommended to regroup both graphics after renaming them (Graphics Group or hotkey Ctrl+G).
Hint: If you define several new extents which are even overlapping, make sure that the name is situated as close as possible to the left bottom corner or group both graphics (select the rectangle and the text and call the function Graphics Group or just press the hotkey Ctrl+G).
