The value of this constant is an integer that will be passed as a bit
flag component of the buttons argument to various
event-handling generic functions such as mouse-left-down if either Alt
key was down when the event occurred. See extended-key for how to tell
whether the right or left key was down.
On the Windows platform, the righthand Alt key will be handled
by Common Graphics only if the reserve-righthand-alt-key configuration option
is nil.
On the Apple Mac, the alt-key corresponds to the Option/Alt key and the meta key corresponds to the Command key (also called the Apple key).
