When to use it
The box with an arrow escaping through the corner: this link leaves the current site or app. Use it inline after the link text at roughly cap height, and reserve it for genuinely external destinations — decorating every link kills the signal. Heroicons names it arrow-top-right-on-square and Phosphor arrow-square-out, so don't give up when 'external' returns nothing.
Reach for the box-with-an-outbound-arrow to warn that a link leaves the current context — opens a new tab, or jumps to another site. It's an honesty marker: it sets the expectation that the user is about to navigate away. Keep it clear of share, which sends content to people, and of download, which lands a file on the device. It annotates a link; it is rarely a standalone button.
