I want a certain keypress act as forward-sexp in "programming
language" modes, and as forward-sentence (sp?) in other modes
(likewise for go-to-function-begin (sp?) and forward-paragraph (sp?)).

So there must be some code which decides "which type" is the given
major mode.  I would prefer the bulk of the decision to be made
programmatically, THEN let the user override if the auto-choice was
wrong.  Anyone with ideas how to do this?

Thanks,
Ilya

P.S.  In addition to sexp/sentence and function/paragraph, are there
      other "merges" one can do to do navigation?
