The keyboard key
component exists to show which key or combination of keys
performs a given action.
The action itself should be further explained in accompanying content. It
renders a <kbd>
element.
All shortcuts should do their best to match what appears on the user’s keyboard.
The only punctuation you should need is the + to indicate that a combination of keys will activate the shortcut.
For a sequence of keys where one must follow the other, write "then" in between. Stick to lowercase to match the non-letter keys.
If two different keys can execute the same action or the shortcut itself may look different on the user’s keyboard, write "or" in between.
