unable to find all public scope input and outputs

Greetings,

I am taking over someone's code that has uses public scope tags. I am not able to find all the tags that read the transmitter tag. I do a find and then try find next (F3). I get a couple but not all receiver tags. I can see some receivers that where not found by find by manually looking through a lot of code. Very frustrating to have to go through all the code looking for these tags. Any fix or method that works at finding tags

Using 6.04.4.5879

Thank you
