In some cases geometry is hard to select - perhaps it is overlapping, or too close to see properly. In such cases the Confirmed Selection technique can be used in the Processing and Geometry (see Geometry Editor selection) editors to select the items you want.
Confirmed Selection is performed by holding down the ALT key as you select using direct or enclosed/crossing rectangle selection techniques.
After selecting an item, a dialog box asks if you want to add that item to the selection, for all items that would normally have been selected.
