In the modules that provide a 3D view of your molecule (currently ADFinput, ADFview, ADFmovie) you can make selections using the mouse.
Click on an object: make a new selection with it
Click in space: clear selection
Shift-Click on object: add or remove it from the selection
Shift-Drag in space: add all objects within the rectangle to the selection
Pop-up menus: Select all similar elements or all bonds by using the pop-up menus
In some modules there are additional ways to select objects using menu commands. Furthermore, one can select atoms from the list in the coordinates window.
