If you use an alternate text editor, you apply formatting by entering format codes. You can underline text, add a line over text, and create stacked text. You also can change color, font, and text height. You can change the spaces between text characters or increase the width of the characters themselves. To apply formatting, use the format codes shown in the Table: Format Codes for Paragraphs.
Braces can be nested up to eight levels deep.
You also can use control codes to add special characters, such as tolerance or dimensioning symbols. See MTEXT.
