+ * Either the grab_window is an ancestor of (or is) the focus window, or the
+ * grab_window is a descendant of the focus window and contains the pointer.
+ * 
+ * A passive grab on the same key combination does not exist on any ancestor of
+ * grab_window.
+ * 
+ * The interpretation of the remaining arguments is as for XGrabKeyboard.  The active grab is terminated
+ * automatically when the logical state of the keyboard has the specified key released (independent of the
+ * logical state of the modifier keys), at which point a KeyRelease event is reported to the grabbing window.
+ * 
+ * Note that the logical state of a device (as seen by client applications) may lag the physical state if
+ * device event processing is frozen.
+ * 
+ * A modifiers argument of AnyModifier is equivalent to issuing the request for all possible modifier combinations (including the combination of no modifiers).  It is not required that all modifiers specified
+ * have currently assigned KeyCodes.  A keycode argument of AnyKey is equivalent to issuing the request for
+ * all possible KeyCodes.  Otherwise, the specified keycode must be in the range specified by min_keycode
+ * and max_keycode in the connection setup, or a BadValue error results.
+ * 
+ * If some other client has issued a XGrabKey with the same key combination on the same window, a BadAccess
+ * error results.  When using AnyModifier or AnyKey, the request fails completely, and a BadAccess error
+ * results (no grabs are established) if there is a conflicting grab for any combination.
