Many commands will prompt you to select objects. The following are acceptable methods of responding to the select objects prompt. When you are finished selecting objects using any one or a combination of these methods, press enter to continue the original command.
TO SELECT OBJECTS:
Click on objects one-at-a-time using the left mouse button.
OR drag a window around the object(s). When dragged from left to right, a selection window will select only those objects completely within the window. When drawn from right to left, a window will select all objects within and contacted by the window.
OR type ALL. Selects everything in the current space.
OR hold down the CTRL key while selecting objects; this has the effect of removing objects from the current selection.
