Its almost what I want. What I really want is a double arrow (==>), and I see that unfortunately latex doesn't have a \xRightarrow (or at least Lyx doesn't recognize it). I tried using the \overset command (\underset just produces a complete mess) and again its almost what I want but it doesnt elongate the arrow to accomodate the label. Oh well, thanks for the tip.
