Next we're going to add text and format the text. Double click on a stencil to enter text.
There is no need to create a text box, since OmniGraffle does this automatically for you.
The default format for text in OmniGraffle is Helvetica twelve point font. The most efficient
way to format is to enter the text on all the stencils, then format all at once. To do this,
click on one of the shapes to select it. Hold down the Shift key, and click on the other shapes
you wish to format. With the text selected (as indicated by highlighted stencils), go to the
style palette, select the font icon and choose the font, style, and size you like.
