How to Write Keyboard Keys with Libertinus
The Libertinus Keyboard font offers a clever way to display keyboard key symbols using ligatures — special character combinations that automatically turn text into a key icon, like Shift. While implementing Libertinus on this site, I found little documentation, so I’ve written a short memo explaining how it works. It includes examples, quirks, and a full list of available key glyphs extracted from the SFD source. A must-read if you’re working with Libertinus, typography, or accessible keyboard icons in web projects.
