When you are getting into thousands of lines of code, there is not alot you can do to avoid having to scroll thru it to find things, though you can do things to reduce the amount of scrolling needed.
What you could do is go thru the code and organize it into functional sections. To aid in the need to scroll to find things, you can make use of keywords as comments in combination with the Find tool (the magnifying glass in the toolbar), and use it to jump to sections.
You could probably break it all down into separate class files, but then it might be even moreso unwieldy for you to have to remember which file you need to look at for different things. Still, for major functional divisions this can be useful.
