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.

C-h f kbd [ENTER]

kbd is a compiled Lisp function in `subr.el'.

(kbd KEYS)

Convert KEYS to the internal Emacs key representation.
KEYS should be a string constant in the format used for
saving keyboard macros (see `edmacro-mode').

Emacs is self-documented, as demonstrated on the response to your
previous inquiry. Additionally, it comes with a manual for the Emacs
Lisp language and for Emacs proper.

To learn more explore the contents of the Help menu in your Emacs.

If your question is about representing key sequences, see the "Key
Sequences" section on the Elisp Manual.

Go to the "Help" menu, then to "More Manuals" and finally to "Emacs Lisp
Reference".

Another way is

C-h i m elisp [INTRO]

It is recommended to first read the "Introduction to Emacs Lisp",
available from the same submenu as the other manual.
