Most of the time, IDEs get these features by calling CLI programs. It's very easy to call CLI programs from VIM/EMACS, and set up bindings to make it very quick. As for code navigation, plugins let you navigate to functions, explore projects / directories, and intelisense.

On the one hand, when developing for a new platform or language, you spend some extra time tweaking on VIM, rather than being able to use the platform developers Eclipse GUI immediately. On the other hand, I've found that being exposed to the command line tools with all their arguments, you are more able to fix problems and automate tasks.
