+Z-order of frames is an ordering of overlapping frames, so that one frame can hide part or all of the another. When two frames overlap, their Z-order determines which one appears on top of the other. The frame with higher z-order appears on the top. When a frame is created its z-order is the highest among the frames in the page. Two frames can't have the same z-order. When focus is requested to a frame, the frame appears on the top of the others but its z-order in the model doesn't change. When the same frame lose focus, it appears on the appropriate layer. The way to change the z-order is with the appropriate halo buttons (at least this is for now). So in this task a halo for increasing and a halo for decreasing the z-order of a frame should be created. If a frame has z-order equal to 4 and its z-order is increased to 5, then the frame which had z-order 5 before that will become with z-order 4.
