## meta-key

This variable is relevant only on the Apple Mac.

The value of this variable 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 the Option key of a Apple Mac was down when a keyboard or mouse event occurs. (The Option key also says "Alt" on it.) On other platforms this variable has the same value as alt-key and has no effect.

For handling the Command key on a Mac (also called the Apple key), use `meta-key`.
