'C-c C-k' (geiser-compile-current-buffer) works most of the time,
however this is not a silver bullet.  For example:

--8<---------------cut here---------------start------------->8---
;;; foo.scm
(define (where-is-foo)
  (display "foo!\n"))

(where-is-foo)
--8<---------------cut here---------------end--------------->8---

'M-.' when the point is on 'where-is-foo' procedure call won't find the
procedure definition even after 'C-c C-k'.  It only works in the context
of a module.

My point is that Geiser should not be expected to be 100% reliable.
'M-x rgrep' is sometimes a helpful complement.  ;)

Thanks,
