Not only can you make simple squares, circles, ovals, and lines, but MS Word provides AutoShapes, a gallery of typical shapes such ... as stars, pentagons, block arrows, etc. A special type of AutoShape, a callout, combines a text box and indicator line and is used to attach explanatory text to a specific part of the document, much as a speech balloon in a comic strip attaches to a character, or a label points to part of a cell or organism in a biology diagram. Other buttons on the ... (view more)
