* A set of bit-flags to indicate the state of modifier keys and mouse buttons

* %GDK_HYPER_MASK or %GDK_META_MASK in the state field of key events.
*
* Note that GDK may add internal values to events which include
* reserved values such as %GDK_MODIFIER_RESERVED_13_MASK. Your code
* should preserve and ignore them. You can use %GDK_MODIFIER_MASK to
* remove all reserved values.
*
* Also note that the GDK X backend interprets button press events for button
* 4-7 as scroll events, so %GDK_BUTTON4_MASK and %GDK_BUTTON5_MASK will never
