You are not telling us how exactly you tried to expand that, what you
expected and what happened instead, so I’ll venture a guess: You’re
pressing Ctrl+semicolon and it does not expand. Instead, Emacs tells
you “C-; is undefined”.

According to docs[1], you need the ‘# binding:’ (not ‘# key:’) keyword
to set the key that will expand the snippet. Alternatively, you could
type your snippet’s key (that’s capital letter C, followed by hyphen,
followed by semicolon), then press TAB, and it might expand; but I
guess that’s not what you meant to do.

Also I hope you’re doing that in a GUI frame and not in a terminal.
Not many terminals can faithfully deliver the Ctrl+semicolon
keystroke.
