C-h k C-x C-o will tell you waht function is bound to C-x C-o.
(global-set-key (kbd "C-a") 'that-function) in you ~/.emacs will bind
C-a to that function.

Here, C-x C-o is bound to delete-blank-lines, so:
(global-set-key (kbd "C-a") 'delete-blank-lines)
You can activate it immediately typing C-x C-e after it.
