Smart Key - Lisp Source Code

bash
When pressed on a Lisp symbol within any of these types of buffers
(Lisp code, debugger, compilation, *Warnings*, *Flymake log* and *Flymake
diagnostics, help or change-log-mode buffers) on an Emacs Lisp bound
identifier:
  ACTION KEY
     Jumps to the definition of any selected Lisp construct.  This includes
     Hyperbole implicit button type and action type references.  If on an
     Emacs Lisp require, load, or autoload clause and the (find-library)
     function is defined, jumps to the library source, if possible.
  ASSIST KEY
     Jumps to the next tag matching an identifier at point unless
     the identifier is an Emacs Lisp symbol, then:
       1. if it contains an in-memory Hyperbole button, display the buttons
          attributes in a help buffer.
       2. otherwise, display the identifier’s documentation in a help buffer.
