  @{@index{Meta} Most keyboard and mouse mappings are inserted into a keymap by

    ``meta'' combinations require special attention.  The @racket["m:"] prefix
    recognized by @method[keymap% map-function] applies only to the Meta key
    that exists on some keyboards.  By convention, however, ``meta''
    combinations can also be accessed by using ``ESC'' as a prefix.
    
    This procedure binds all of the key-bindings obtained by prefixing
    @racket[key] with a meta-prefix to @racket[func] in @racket[keymap].
    
    If @racket[alt-as-meta-keymap] is a @racket[keymap%] object, then the

    signals an error.
    
    If @racket[mask-control?] is @racket[#t],
    then the result strings include @racket["~c:"] in them.
    This is important under Windows where international keyboards
    often require characters that are unmodified on US keyboards to
    be typed with the AltGr key; such keys come into the system as
    having both the control and the meta modified applied to them and, 
    generally speaking, keybindings should not change the behavior of
    those keys.})
