## *ignore-mouse-x-buttons*

When the value of this variable is true, Common Graphics excludes bits for the two X buttons that some mice have from the button-state argument that is passed to event-handling generic functions such as virtual-key-down, mouse-left-down, and cell-click. It also excludes these buttons from the values returned by the functions mouse-button-state, down-keys, and down-key-names.

The value of this variable is true initially, to provide backward compatibility to existing Common Graphics applications that do not expect these bits. If you would like to use X buttons in an application, then you can set this variable to `nil`.
