- The _X_G_r_a_b_D_e_v_i_c_e_K_e_y request establishes a passive grab. In
- the future, the device is actively grabbed (as for
- _X_G_r_a_b_D_e_v_i_c_e, the last-device-grab time is set to the time at
- which the Key was pressed (as transmitted in the
- _D_e_v_i_c_e_K_e_y_P_r_e_s_s event), and the _D_e_v_i_c_e_K_e_y_P_r_e_s_s event is
- reported if all of the following conditions are true:
-
- +o The device is not grabbed, and the specified key is
- logically pressed when the specified modifier keys are
- logically down, and no other keys or modifier keys are
- logically down.
-
- +o The grab_window is an ancestor (or is) the focus window
- OR the grab window is a descendant of the focus window
- and contains the device.
-
- +o The confine_to window (if any) is viewable.
-
- +o A passive grab on the same key/modifier combination
- does not exist on any ancestor of grab_window.
-
- The interpretation of the remaining arguments is as for
- _X_G_r_a_b_D_e_v_i_c_e . The active grab is terminated automatically
- when the logical state of the device has the specified key
- released.
-
- Note that the logical state of a device (as seen by means of
- the X protocol ) may lag the physical state if device event
- processing is frozen.

- If the key is not _A_n_y_K_e_y, it must be in the range specified
- by min_keycode and max_keycode as returned by the
- _X_L_i_s_t_I_n_p_u_t_D_e_v_i_c_e_s request. Otherwise, a _B_a_d_V_a_l_u_e error
- results.
-
- This request overrides all previous grabs by the same client
- on the same Key/modifier combinations on the same window. A
- modifier of _A_n_y_M_o_d_i_f_i_e_r is equivalent to issuing the grab
- 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
- key of _A_n_y_K_e_y is equivalent to issuing the request for all
- possible keys. Otherwise, it is not required that the
- specified key currently be assigned to a physical Key.
-
- If a modifier_device of NULL is specified, the X keyboard
- will be used as the modifier_device.
-
- If some other client has already issued a _X_G_r_a_b_D_e_v_i_c_e_K_e_y
- with the same Key/modifier combination on the same window, a
- _B_a_d_A_c_c_e_s_s error results. When using _A_n_y_M_o_d_i_f_i_e_r or _A_n_y_K_e_y ,
- the request fails completely, and a _B_a_d_A_c_c_e_s_s error results
- (no grabs are established) if there is a conflicting grab
- for any combination. _X_G_r_a_b_D_e_v_i_c_e_K_e_y has no effect on an
- active grab.
-
- _X_G_r_a_b_D_e_v_i_c_e_K_e_y can generate _B_a_d_A_c_c_e_s_s, _B_a_d_C_l_a_s_s, _B_a_d_D_e_v_i_c_e,
- _B_a_d_M_a_t_c_h, _B_a_d_V_a_l_u_e, and _B_a_d_W_i_n_d_o_w errors. It returns
- _S_u_c_c_e_s_s on successful completion of the request.
-
- The _X_U_n_g_r_a_b_D_e_v_i_c_e_K_e_y request releases the passive grab for a
- key/modifier combination on the specified window if it was
- grabbed by this client. A modifier of _A_n_y_M_o_d_i_f_i_e_r is
- equivalent to issuing the ungrab request for all possible
- modifier combinations, including the combination of no
- modifiers. A Key of _A_n_y_K_e_y is equivalent to issuing the
- request for all possible Keys. _X_U_n_g_r_a_b_D_e_v_i_c_e_K_e_y has no
- effect on an active grab.
-
- If a modifier_device of NULL is specified, the X keyboard
- will be used as the modifier_device.
-
- _X_U_n_g_r_a_b_D_e_v_i_c_e_K_e_y can generate _B_a_d_D_e_v_i_c_e, _B_a_d_M_a_t_c_h, _B_a_d_V_a_l_u_e
- and _B_a_d_W_i_n_d_o_w errors.

- _B_a_d_D_e_v_i_c_e An invalid device was specified. The specified
- device does not exist or has not been opened by
- this client via _X_O_p_e_n_I_n_p_u_t_D_e_v_i_c_e. This error
- may also occur if the specified device is the X
- keyboard or X pointer device.

- _B_a_d_M_a_t_c_h This error may occur if an _X_G_r_a_b_D_e_v_i_c_e_K_e_y

-
- _B_a_d_V_a_l_u_e Some numeric value falls outside the range of
