To enlarge the display of the forms in Forms View, click the magnifying glass buttons located in the upper right corner of the program window. They are on the right end of the blue bar across the top of the form (right of the form name). Cick the magnifying glass with the plus or minus signs (+ or -) to increase or decrease the display size of the form.
In Q&A View, you may use the keyboard commands Ctrl + = (press the Ctrl key and the equal sign key together) or Ctrl + "+" (press the Ctrl key and the plus sign on the number pad together) to enlarge, and Ctrl + - (press the Ctrl key and either the hyphen key or minus sign key on number pad together) to reduce. You may also hold the Ctrl key and use the scroll wheel on the mouse to enlarge or reduce the font size.
Ctrl + 0 (Ctrl key plus the zero key) will return to the default size setting.
