Text Tool  
    The Text Tool is used to either highlight a segment of text in a text 
box, or position the text insertion point so that you can type new text 
into a text box. When the text tool is selected, the pointer changes into 
an I-beam when it is moved over the document window. To 
highlight a text segment, click and hold the mouse button at one end of
the text segment and drag to the other end. To position the text insertion 
point, move the pointer (I-beam) to the location at which you want to 
enter new text and click once. The text insertion point is indicated by a 
vertical bar.
