It often takes me 20-30 minutes to edit a single line of code. Understanding why I need to change the program, what the effects of making that change are, determining which line of the code to edit, figuring out whether I need to edit or refactor, spending time in a REPL to test the proposed changes...

I just use the mouse.

For me, part of getting that understanding is navigating the code and I do not always have room for another window on my screens.

It seems we have different approaches to working on code, or perhaps we just use different language. The main languages I currently work in are: Common Lisp, Python, JavaScript and C++.
