Then I can only suggest reading those sections of the Emacs manual and
if necessary looking at the source code of the functions (I think most
of the are Lisp functions in simple.el).  Then maybe you can put
something together for yourself, though I suspect it won't be easy to
get something that works as well as the existing commands.  One other
tip: if what you really want to do is navigate between existing
functions or other named pieces of code, then using `M-.' and `M-,' is
probably the most efficient way, see (info "(emacs) Looking Up Identifiers").
