feature key
     
         (Or "flower", "pretzel", "clover", "propeller",
        "beanie" (from propeller beanie), {splat}, "command key") The
        {Macintosh} key with the cloverleaf graphic on its keytop.
     
        The feature key is the Mac's equivalent of an {alt} key (and
        so labelled on some Mac II keyboards).  The proliferation of
        terms for this creature may illustrate one subtle peril of
        iconic interfaces.
     
        Many people have been mystified by the cloverleaf-like symbol
        that appears on the feature key.  Its oldest name is "cross of
        St. Hannes", but it occurs in pre-Christian Viking art as a
        decorative motif.  Throughout Scandinavia today the road
        agencies use it to mark sites of historical interest.  {Apple
        Computer} picked up the symbol from an early {Macintosh}
        developer who happened to be Swedish.  Apple documentation
        gives the translation "interesting feature"!
     
        There is some dispute as to the proper (Swedish) name of this
        symbol.  It technically stands for the word "sev"ardhet"
        (interesting feature) many of these are old churches.  Some
        Swedes report as an idiom for it the word "kyrka", cognate to
        English "church" and Scots-dialect "kirk" but pronounced
        /shir'k*/ in modern Swedish.  Others say this is nonsense.
