Some of the questions / answers here have cool images of a key to press, like Esc, but it looks like a key.
How do I do that? I cannot see it documented in the editing FAQ or in https://superuser.com/editing-help or in the Markdown documentation.
Update:
With the answers below, this should do it: <kbd>Ctrl</kbd>
Ctrl
And it does!
It also seems that the request to add this to the documentation has not yet been completed.
