The 'kbd element denotes user input. Typically this is keyboard input (hence “kbd”), but it may also be used to represent other user input, e.g. voice commands or gestures.
This example uses the
kbd element to convey a command line command to the user.
<p>Type the command <kbd>git status</kbd> to see the working tree status.</p>
This example illustrates using
kbd to indicate keystrokes.
<p>Press <kbd><kbd>Ctrl</kbd>+<kbd>s</kbd></kbd> to save your document.</p>
The kbd element is a phrasing-level element. It must not contain block-level elements, but it can contain other phrasing-level elements.
When the kbd element is nested inside a samp element, it represents the input as it was echoed by the system.
When the kbd element contains a samp element, it represents input based on system output, for example invoking a menu item.
When the kbd element is nested inside another kbd element, it represents an actual key or other single unit of input as appropriate for the input mechanism (see Example 2).
