Yahoo Mail offers several ways to make text stand out when composing a message, along with keyboard shortcuts to apply underline, bold, and italic formatting quickly.

Instructions in this article apply to the standard web version of Yahoo Mail. Yahoo Mail Basic and the Yahoo Mail mobile app offer limited formatting options.
