title: How do I show the "up" and "down" arrow keyboard key in GitHub markdown?
body: <p>How do I show the "up" and "down" arrow keyboard keys (←, ↑, → and ↓) in GitHub markdown? So far I am able to show <kbd>up</kbd> and <kbd>down</kbd>. But how do I show the arrow symbol instead the text "up" and "down"?</p>
