Thanks for the prompt reply. Well, of course I can write \dfrac from scratch, but I do not want to do that.
I want to modify an existing math equation in text model. In LyX, I can modify an existing equation in WYSIWYG mode, but I do not know how to modify an equation by modifying the Latex code directly.

For example, if I enter a fraction in math environment using back slash like \frac, is there a way to edit this Latex code and make it \dfrac simply by placing “d” in front of “f”? Baris Erkus Did you try entering \dfrac while in math mode? It works for me. -- David L. Johnson Department of Mathematics Lehigh University
