This one's short (ish?) and sweet. It describes how to make your own global key bindings for functions of your choice in Emacs.
C-h bin Emacs. This will bring up a list of all the current keybindings.
C-s [KEYBINDING YOU WANT WRITTEN OUT]to double check that the shortcut isn't taken using search. For example to check that
C-c tisn't taken type
C-s C-c t.
cl ;; [USEFUL COMMENTS] (global-set-key (kbd "[KEYSTROKES WRITTEN OUT]") '[FUNCTION NAME])
For example to set C-c g to trigger goto-line:
;; Define C-c g as a shortcut for goto-line. (global-set-key (kbd "C-c g") 'goto-line)
That's all there is to it. A little bit more about setting key binding in the GNU Emacs Manual.
If you want to use a key that you don't know the code of simply press,
C-c h [KEY OF INTEREST]. For example
C-c h [F5] shows: " is undefined", so I would use
Ok, that's it, you don't have to read the rest. The rest is just the usual quagmire associated with most things in Emacs.
A side note is that there are multiple ways of refering to keybindings in emacs. In this example, I make use of the kbd macro. The kbd macro converts keystrokes written out using M-, C-, etc. into a form that can be passed as an argument to global-set-key. Instead of using kbd, you can also write out your keystroke combinations using a Lisp string. This will only work , "for ASCII characters and Meta-modified ASCII characters."
;; Alternate definition of C-c g as a shortcut for goto-line using Lisp strings. (global-set-key "\C-cg" 'goto-line)
Finally, you can use a Lisp vector. Vectors are written in square brackets, and characters in vectors are written with a question mark and slash in front of them.
;; Alternate definition of C-c g as a shortcut for goto-line using Lisp vectors. (global-set-key [?\C-c ?\g] 'goto-line)
I usually try the kbd method first, since it will usually work. You can use array to make use of strange keytrokes. Simply type C-q and the keystroke you're interested in to insert the code for it.
For example, if we type C-q C-c we get ^C, and C-q g gives simply g, so the example above can also be written like:
;; Another alternate definition of C-c g as a shortcut for goto-line using Lisp vectors. (global-set-key [?^C ?g] 'goto-line)
I have to say, that there are some keystrokes whose codes I have trouble getting emacs to understand this way, but using
C-c h and kbd will usually do the trick. There's certain keys you won't be able to use. For example if you're on a
Windows system and you hit the Windows key while using Emacs in a terminal, you'll get the Start menu on Windows instead
of a keystroke sent to Emacs.
