I've got this in my .emacs.  It does a research regexp Isearch to look for a
'{' as the only character on a line.  I also have a corresponding one using
regexp Isearch to move forward looking for a '}' on a line. (I use these in C
programming).

These don't stick after call Isearch.  Maybe this would be a step in the right
direction for you.


(fset 'start-of-function [?\C-u ?\C-R ?^ ?{ ?$ ?\C-m])
(global-set-key (kbd "C-{") 'start-of-function)
