Find without Replace in Jupyter Notebook

I am fairly new to using the Jupyter notebook and quite like it but, I find that many times I just need to “Find” something (like a function name for example) in my code. The only “Find” I can see in the notebook is “Find and Replace” and, many times, I don’t want to replace anything just figure out which line a given piece of text is on. Even if “Find and Replace” showed line numbers, that would be useful but I can’t seem to even get that. Am I missing something?
