For elisp, you can use something like this:

--8<---------------cut here---------------start------------->8---
(progn

  (require 'thingatpt)
  
  (defun my-find-symbol-at-point ()
    "Find the definition of the symbol at point."
    (interactive)
    (let ((sym (symbol-at-point)))
      (funcall (pcase sym
		 ((pred facep)           #'find-face)
		 ((pred symbol-function) #'find-function)
		 (_                      #'find-variable))
	       sym)))
  
  (global-set-key [(shift return)] #'my-find-symbol-at-point))
--8<---------------cut here---------------end--------------->8---
