Text - selecting and deselecting text in large blocks of selected text - if you have selected a large block of text and find you have not selected enough text or have selected too much and don't want to start all over again, use the shift-click method. Position the I-beam at either the beginning or end of the selected text, hold down the Shift key, click the mouse and drag in the appropriate direction. (You can use this method only once and only at one end or other of a given selection.)
