* GdkModifierType:

* @GDK_LOCK_MASK: a Lock key (depending on the modifier mapping of the
* X server this may either be CapsLock or ShiftLock).
* @GDK_CONTROL_MASK: the Control key.
* @GDK_MOD1_MASK: the fourth modifier key (it depends on the modifier
* mapping of the X server which key is interpreted as this modifier, but
* normally it is the Alt key).
* @GDK_MOD2_MASK: the fifth modifier key (it depends on the modifier
* mapping of the X server which key is interpreted as this modifier).
* @GDK_MOD3_MASK: the sixth modifier key (it depends on the modifier
* mapping of the X server which key is interpreted as this modifier).
* @GDK_MOD4_MASK: the seventh modifier key (it depends on the modifier
* mapping of the X server which key is interpreted as this modifier).
* @GDK_MOD5_MASK: the eighth modifier key (it depends on the modifier
* mapping of the X server which key is interpreted as this modifier).
* @GDK_BUTTON1_MASK: the first mouse button.
* @GDK_BUTTON2_MASK: the second mouse button.
* @GDK_BUTTON3_MASK: the third mouse button.
* @GDK_BUTTON4_MASK: the fourth mouse button.
* @GDK_BUTTON5_MASK: the fifth mouse button.
* @GDK_SUPER_MASK: the Super modifier. Since 2.10
* @GDK_HYPER_MASK: the Hyper modifier. Since 2.10
* @GDK_META_MASK: the Meta modifier. Since 2.10
* @GDK_RELEASE_MASK: not used in GDK itself. GTK+ uses it to differentiate
* between (keyval, modifiers) pairs from key press and release events.
* @GDK_MODIFIER_MASK: a mask covering all modifier types.
*
* A set of bit-flags to indicate the state of modifier keys and mouse buttons
* in various event types. Typical modifier keys are Shift, Control, Meta,
* Super, Hyper, Alt, Compose, Apple, CapsLock or ShiftLock.
*
* Like the X Window System, GDK supports 8 modifier keys and 5 mouse buttons.
*
* Since 2.10, GDK recognizes which of the Meta, Super or Hyper keys are mapped
* to Mod2 - Mod5, and indicates this by setting %GDK_SUPER_MASK,
* %GDK_HYPER_MASK or %GDK_META_MASK in the state field of key events.
