 `@kbd'{KEYBOARD-CHARACTERS}
 ---------------------------
 
   Use the `@kbd' command for characters of input to be typed by users.
 For example, to refer to the characters `M-a', write
 
      @kbd{M-a}
 
 and to refer to the characters `M-x shell', write
 
      @kbd{M-x shell}
 
   The `@kbd' command has the same effect as `@code' in Info, but by
 default produces a different font (slanted typewriter instead of normal
 typewriter) in the printed manual, so users can distinguish the
 characters they are supposed to type from those the computer outputs.
 
   Since the usage of `@kbd' varies from manual to manual, you can
 control the font switching with the `@kbdinputstyle' command.  This
 command has no effect on Info output.  Write this command at the
 beginning of a line with a single word as an argument, one of the
 following:
 `code'
      Always use the same font for `@kbd' as `@code'.
 
 `example'
      Use the distinguishing font for `@kbd' only in `@example' and
      similar environments.
 
 `distinct'
      (the default) Always use the distinguishing font for `@kbd'.
 
   You can embed another @-command inside the braces of an `@kbd'
 command.  Here, for example, is the way to describe a command that
 would be described more verbosely as "press an `r' and then press the
 <RET> key":
 
      @kbd{r @key{RET}}
 
 This produces: `r <RET>'
 
   You also use the `@kbd' command if you are spelling out the letters
 you type; for example:
 
      To give the @code{logout} command,
      type the characters @kbd{l o g o u t @key{RET}}.
 
 This produces:
 
      To give the `logout' command, type the characters `l o g o u t
      <RET>'.
 
   (Also, this example shows that you can add spaces for clarity.  If you
 really want to mention a space character as one of the characters of
 input, write `@key{SPC}' for it.)
