@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; they are all in upper case:

SPC

Space

RET

Return

LFD

Linefeed

TAB

Tab

BS

Backspace

ESC

Escape

DEL

Delete

SFT

Shift

CTL

Control

META

Meta

There are subtleties to handling words like `meta' or `ctl' 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. This is because Meta-a refers to keys that you press on a keyboard, but META refers to a key without implying that you press it. In short, use @kbd for what you do, and use @key for what you talk about: "Press @kbd{M-a} to move point to the beginning of the sentence. The @key{META} key is often in the lower left of the keyboard."
