But would you call that navigation "jumping to method's interface(s)"?

AFAIK, in Java you still call the method definitions inside an interface 
(file/entity) "method declarations". Unless it's a "default" method, 
available with Java 8+.

Clojure is similarly able to define Java interfaces (with no special 
term for methods enumerated inside, AFAIK), or Protocols (methods inside 
are called "protocol methods", but it would probably be fair to call 
them "declarations" as well).

More importantly, I guess, in both Java or C/C++ you can have method 
declarations that are not part of an "interface". E.g. you have some 
class with abstract method or several.

The LSP protocol uses the term "declaration", so we probably won't make 
too much of a mistake reusing that term. But, indeed, it sounds similar 
enough to "definition".
