It is difficult to convey information about a complex thing through a simple image. Nevertheless, the current tooltip is absolutely correct and the current icon conveys better the idea than a misleading icon about sizes. > > It's a matter of style not size.

No, please, you must have a look at pages 140 and 141 in the TeXbook, where all of this is explained in detail. You will see that sizes are of absolutely secondary importance in this case. Indeed, I could simply highlight a formula in LyX and choose a different size for it using the "ab" toolbar button. -- Enrico
