Then I'd suggest "show definition" instead of "navigate".  The latter
has no useful meaning in this context, and just confuses.

"go to definition" should be the clearest option, then.

...Except the xref interface is also supposed to be used for "apropos" and "find references". The latter, though not implemented for the two current backends, would be reasonably easy to do for certain environments like SLIME. "definition" won't be the right term then. Any suggestions?

I don't really understand the difference between the various options,

I'm afraid you'll have to spend the effort to understand it (but feel free to ask questions). AFAICT, the audience for this feature is just a few people, and myself is not among them. So far, I don't have the proper requirements to work with.

Come on, in each case that's just a few lines of Lisp you need to look at, and maybe try.

so my suggestion would be to start with something that looks
promising, and then see if users like that.  The important thing is
implement something; just enumerating the alternatives is not enough.

Messages 32 and 41 include functional implementations you can try. The patches that would go into Emacs won't be much different, we'd just have to decide on code organization.
