    	when MULTI_FRAME isn't #defined.  People might find it
    	necessary for writing correct programs, even when the programs
    	don't explicitly use multiple frames.
    	(read_char, kbd_buffer_store_event, kbd_buffer_get_event): No need
    	to test MULTI_FRAME before setting Vlast_event_frame.
    	(syms_of_keyboard): DEFVAR Vlast_event_frame whether or not
    	MULTI_FRAME is defined.
            * keyboard.c: Add switch-frame events.
    	(Qswitch_frame): New event header symbol.
    	(head_table): Include Qswitch_frame in the table of event heads.
    	(kbd_buffer_get_event): Detect when a frame switch has occurred,
    	and return a frame switch event before the enqueued event.
    	(make_lispy_switch_frame): New function.
    	(unread_switch_frame): New variable.
    	(read_key_sequence): Don't throw away the key sequence if the user
    	switches frames in the middle of the sequence.  Instead, when we
    	receive a switch-frame event in the middle of a key sequence, save
    	it, and stuff it into unread_switch_frame when the sequence
    	is complete.
    	(read_char): If unread_switch_frame is set, return that value.
    	(command_loop_1): No need to check Vlast_event_frame and select
    	new frames here; that's taken care of by switch-frame events now.
    	(syms_of_keyboard): Initialize and staticpro unread_switch_frame.
    	* keyboard.c (follow_key, read_key_sequence): Call access_keymap
    	with T_OK true.
    	* keyboard.c (apply_modifiers): Copy the value of BASE's
    	Qevent_kind property to the new symbol.
    	* keyboard.c (syms_of_keyboard): Qevent_kind should be initialized
    	to intern ("event-kind"), not intern ("event-type").
