;; "What am I looking at?"
;;
;; This module helps you answer that question. It helps you look up whatever
;; you're looking at.
;;
;;   + `+jump/definition': a jump-to-definition that should 'just work'
;;   + `+jump/references': find a symbol's references in the current project
;;   + `+jump/online'; look up a symbol on online resources, like stackoverflow,
;;     devdocs.io or google.
;;
;; This module uses `xref', an experimental new library in Emacs. It may change
;; in the future. When xref can't be depended on it will fall back to
;; `dumb-jump' to find what you want.
