Selecting Text using Mouse and Shift Key.

You already know that you can use the mouse to select text by holding down the left mouse button and dragging the mouse to make a selection. There is an even quicker way to select text using the mouse, however. This is done in the following manner:

Position the insertion point where you want the selection to begin. 

Move the mouse cursor so it points to where you want the selection to end. 

Hold down the Shift key as you click once on the left mouse button.
