* 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
|

* be set.
