What is a good Perl code navigator?

Question

I am going to write some plugins for a rather huge Perl project. Now I wanted to get an idea of ​​the project by reading interesting sections of the code. But I do not have a good code navigator. Some features that I would like to see:

• right click on the subtitle and go to sub
• find all places where sub is called
• find all places where the variable is used

Is there anything that does this for free?

EDIT: Also, I would like to go forward / backward, so after switching to sub, I can pick up where I left off.
