It is for use in text, like "2nd", "Mme", etc. (Well that's superscript)

I am not against it... as long as we remember that it isn't "the right way". I 
am also not against writing "E = mc^2" using text... only math is already 
available in LyX so this hack isn't needed.

I, from my side, rhetorically don't understand why you are against using math _ 
^ for chemistry... a hack is a hack is a hack ;-)

But I agree that \textsuper/sub is useful and should be implemented.
