`@key'{KEY-NAME}
----------------

  Use the `@key' command for the conventional name for a key on a
keyboard, as in:

     @key{RET}

  You can use the `@key' command within the argument of an `@kbd'
command when the sequence of characters to be typed includes one or
more keys that are described by name.

  For example, to produce `C-x <ESC>' you would type:

     @kbd{C-x @key{ESC}}

  Here is a list of the recommended names for keys:

    SPC
          Space

    RET
          Return

    LFD
          Linefeed (however, since most keyboards nowadays do not have
          a Linefeed key, it might be better to call this character
          `C-j'.

    TAB
          Tab

    BS
          Backspace

    ESC
          Escape

    DEL
          Delete

    SHIFT
          Shift

    CTRL
          Control

    META
          Meta

  There are subtleties to handling words like `meta' or `ctrl' that are
names of shift keys.  When mentioning a character in which the shift key
is used, such as `Meta-a', use the `@kbd' command alone; do not use the
`@key' command; but when you are referring to the shift key in
isolation, use the `@key' command.  For example, write `@kbd{Meta-a}'
to produce `Meta-a' and `@key{META}' to produce <META>.
