I know.

It'll take me one level up, which is not sufficient to answer my question, and by the time I find my bearings again, I have to jump back down a couple levels.

I've done a lot of this, both for Common Lisp codebases in Emacs, and for Java codebases in IntelliJ. Having to jump around and remember stuff eats into "7 ± 2" short-term memory limit that you need for the code you're working on.

(With Emacs, it's at least a tad easier to split the window to have 4+ different in view at the same time.)

Yeah, I like to use a couple of big monitors plus my laptop screen, and have all the relevant code visually accessible at once.
