To change the internal margin of a text box, right click on the border of the text box. From the drop-down menu, select "Format Shape". Under "Shape Options" choose the icon of the text box with arrows (Size & Properties). Click "TEXT BOX" and enter the desired margins. (In 2007, set the internal margin by selecting "Text Box" from the left side menu, select "Text Box". Under "Internal Margin" you can set the left, right, top and bottom margins as desired.) If you set each margin to 0.01", a text box using Arial 10 point font that is 0.7" by 1.0" will allow four lines of text.
