How to search for code in the theme file editor for all the files?


Previous site admin added some JS code that I now need to remove. The problem is:

1. Was added by hand to any of the template files
2. I don’t know where
3. Prev admin not available for comments
4. Can’t access server shell to do a proper grep
5. I tried looking at the obvious files but the code is not there
6. Yes, the code is being rendered in the main page.
7. It’s not a plugin

Is there any way to search all theme files from the admin without shell access? This site is hosted in []( can’t do shell access afaik.


EDIT: added #7
