DISPLAY	tions are:
	TOP OF LIST — Move the selection cursor to the top (first) memory loca-
	tion.
	PAGE UP — Move the selection cursor to the top of the previous trace
	memory location page. Each page contains 15 trace memory locations.
	PAGE DOWN — Move the selection cursor to the top of the next trace mem-
	ory location page.
	BOTTOM OF LIST — Move the selection cursor to the bottom (last) memory
	location.
	DELETE TRACE — Delete the selected trace from memory. This option is
	not available when using Trace Overlay.
