The reason I'm asking is trivial, but I can't come up with a better place to ask.

I bought a keyboard that has Super keys with the vendor logo printed on them.

I've been meaning to replace them with the Windows key but I was wondering if there was another symbol I could use since I'm not really tied to Windows.

  • You may use something like ♃, the glyph of Jupiter, or the I Ching hexagram for "before completion".

  • I'd use the OS X Command key symbol ⌘ – while it's sort of associated with OS X, that's practically just because nobody else uses it. It's not like Apple has a trademark on it, to my knowledge. Plus, it has a standardized Unicode code point! en.wikipedia.org/wiki/Looped_square

  • Have you considered using the user agent to determine what operating system the user is on, then changing the symbol for the super key accordingly?

Common symbols for the super key are OS-specific.

From this answer elsewhere on StackExchange and Wikipedia it doesn't seem like there is an icon other than the Windows and Mac platform specific ones. If you know which OS you will use or have a preference, I would recommend one of those.

An alternative could be to use the obsolete meta key symbol, which was a diamond: ◆. It basically worked the same way as the Windows or Mac command keys, but it is unlikely that someone would recognize that symbol on a modern keyboard.

    Agreed. The very fact that OP is asking this question supports the idea that there effectively isn't. Picking the diamond might be a good solution, as long as there's an explanation of what it represents. Oct 4, 2018 at 20:16

I'd use the OS X Command key symbol, .

Yes, it's traditionally associated with OS X, but that's just because nobody else uses it. I don't believe Apple has a trademark on it or anything like that.

As an added bonus, it even has a Unicode code point – U+2318.


There isn't any universal super key button design due to the history of computers' competition and growth.

Because I don't like Windows' principle and occasionally swap to GNU/Linux platforms, I replaced my superkey buttons to blank ones.
