sometimes called a left single ``curved quote'' or ``curly quote''.
Similarly, @kbd{C-x 8 ]}, @kbd{C-x 8 @{} and @kbd{C-x 8 @}} insert the
curved quotes @t{’}, @t{“} and @t{”}, respectively. Also, a working
-Alt key acts like @kbd{C-x 8}; e.g., @kbd{A-[} acts like @kbd{C-x 8 [}
-and inserts @t{‘}. To see which characters have @kbd{C-x 8}
-shorthands, type @kbd{C-x 8 C-h}.
+@key{Alt} key acts like @kbd{C-x 8} (unless followed by @key{RET});

Alternatively, you can use the command @kbd{C-x 8 @key{RET}}
(@code{insert-char}). This prompts for the Unicode name or code-point
called @key{Super}, @key{Hyper}, and @key{Alt}. Few terminals provide
ways to use these modifiers; the key labeled @key{Alt} on most
keyboards usually issues the @key{Meta} modifier, not @key{Alt}. The
-standard key bindings in Emacs do not include any characters with
-these modifiers. However, you can customize Emacs to assign meanings
-to them. The modifier bits are labeled as @samp{s-}, @samp{H-} and
-@samp{A-} respectively.

Even if your keyboard lacks these additional modifier keys, you can
enter it using @kbd{C-x @@}: @kbd{C-x @@ h} adds the Hyper flag to
