Kbd

The HTML   element, or keyboard input, produces an inline element displayed in the browser's default monotype font. The font face can be changed using the CSS  property. This element is used to identify user input. This element should only be used if the content indicates text entered from the keyboard. Do not use this element if the aim is solely to render text using a fixed width font. Use CSS or the  element instead.
