@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 modifier keys. When mentioning a character in which the modifier 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 modifier key in isolation, use the @key command. For example, write @kbd{Meta-a} to produce Meta-a and @key{META} to produce <META>.
