In Word 2012, you need to click on the “Home” tab and select the font group. In Word 2008 or older, you need to go to “View” and select Formatting Palette, or click open the formatting palette at the top of the screen and switch to the “Font” tab, if it’s not there already.

If you want to print the document, these markings will not appear.

Click the upper-left box, which should allow you to insert a 1x1 Table. Make it a 2x1 Table if you want any intro text or other content before the underline. Move the pointer over the end of the table to change the length of the line, then select the table by right-clicking, and click Borders and Shading, and then click the Borders tab. Under Setting, select None. Under Style, click the line type, color, and width of the underline that you want in the document. [5] X Research source
