How to rename (refactor) a c macro in eclipse

Question

I'm using Code Composer Studio which is based on eclipse Indigo. My Programm is written in C. I want to rename some macros via context-menu-->refactor-->rename. It is possible to get into "refactor mode" but eclipse refuses to do the refactoring after I press return (the macro name is changed to the old value). Is there a possibility to use the "refactor mode" anyway?

Answer 1

1. Open the rename dialog by typing Alt+Shift+R twice. See whether it works.
2. Use SourceInsight smart rename function.
3. As Basile mentioned, use text editor like Emacas and Vi.
