This command creates a Hiliter button. Hiliter buttons are transparent, but when you clicked on one, it hilites the area beneath itΓÇöeverything white beneath it turns to black, and vice versa. When you release the mouse (with the cursor still within the hilited area) the area beneath the button returns to normal. In chains, a Hiliter button becomes hilited at the point at which it is reached in the chain, and stays hilited until the chain is finished. Thus it is possible to use a chain to hilite several isolated parts of the screen at once, or to create a ripple of hiliting as adjacent hiliter buttons turn on.
