assume I want to replace the command \tilde by \widetilde in my latex file through all the file. Is there a way to do so such that the change affects all the text but avoiding to make all the changes by hand?

\renewcommand{\tilde}{\widetilde}on preamble. – Sigur May 11 '15 at 14:07\renewcommand{\tilde}[1]{\widetilde[#1]}or a\letstatement – May 11 '15 at 14:07\let\oldtilde\tildebefore redefining it to wide tilde. That way, if you ever needed a single exception to the rule, you could call on\oldtildeand get the original behavior. – Steven B. Segletes May 11 '15 at 14:11
