@samp{3}, @samp{=}, and the space character (denoted as @key{SPC}),

Emacs also recognizes control characters that are entered using
@dfn{modifier keys}. Two commonly-used modifier keys are
-@key{Control} (usually labeled @key{Ctrl}), and @key{Meta} (usually
-labeled @key{Alt})@footnote{We refer to @key{Alt} as @key{Meta} for
+@key{Control} (usually labeled @key{Ctrl}), and @key{META} (usually
+labeled @key{Alt})@footnote{We refer to @key{Alt} as @key{META} for
historical reasons.}. For example, @kbd{Control-a} is entered by
holding down the @key{Ctrl} key while pressing @kbd{a}; we will refer
-to this as @kbd{C-a} for short. Similarly @kbd{Meta-a}, or @kbd{M-a}

-characters, e.g., @kbd{C-@key{F1}} or @kbd{M-@key{left}}.

You can also type Meta characters using two-character sequences
starting with @key{ESC}. Thus, you can enter @kbd{M-a} by typing
@kbd{@key{ESC} a}. You can enter @kbd{C-M-a} by typing @kbd{@key{ESC}
-C-a}. Unlike @key{Meta}, @key{ESC} is entered as a separate
+C-a}. Unlike @key{META}, @key{ESC} is entered as a separate
character. You don't hold down @key{ESC} while typing the next
character; instead, press @key{ESC} and release it, then enter the
next character. This feature is useful on certain text terminals

On graphical displays, the window manager might block some keyboard
inputs, including @kbd{M-@key{TAB}}, @kbd{M-@key{SPC}}, @kbd{C-M-d}
