How to run whichever function is bound to a certain key












2















There are a lot of occasions where, by default, the key-binding C-c C-c does something useful - e.g. in org-mode or magit. I would like to take whatever function C-c C-c runs, and bind that function to something like F8, without having to know what specific function is being called under the hood.



Thus: how can I take an existing key-binding, obtain the function which that key-binding would run, and then simply run that function?



(I'm aware it would take me 5 min to just make a list of functions that I'm interested in, and bind them appropriately in the respective modes - but I would nevertheless like to know how to achieve the above)

  • Note that C-c C-c in org-mode runs a generic command (org-ctrl-c-ctrl-c) that then dispatches to different functions, depending on context. The solutions below will get you to the top-level command dispatcher, but if you want to get to the lower level dispatched function, you will have to read the org-ctrl-c-ctrl-c code.

Trivially, with a keyboard macro:



(global-set-key (kbd "<f8>") (kbd "C-c C-c"))


n.b. That's not binding to a function; it's making <f8> issue the key sequence C-cC-c, which will in turn call whatever command it is bound to.



However as the C-cC-c sequence is reserved for major modes (refer to C-hig (elisp)Key Binding Conventions), you can trust that the local keymap will contain the binding of interest, and so you could use that to bind <f8> to the same command.



Here's an example I use to make RET do whatever M-j is bound to in any programming major mode.



(defun my-coding-config ()

  "Common behaviours for programming."

  (local-set-key (kbd "RET") (key-binding (kbd "M-j"))))



(add-hook 'prog-mode-hook 'my-coding-config)

    To find which command C-c C-c runs, you can use key-binding, e.g.,



    (key-binding (kbd "C-x C-f"))
    
;; => find-file


    To run an interactive command from Lisp, you can use call-interactively, e.g.,



    (call-interactively #'find-file)


    (funcall won't work sometimes since it doesn't take care of the interactive spec.)



    So maybe the following does what you want



    (defun your-ctrl-c-ctrl-c ()
    
  (interactive)
    
  (let ((command (key-binding (kbd "C-c C-c"))))
    
    (when command
    
      (call-interactively command))))
    

    
(global-set-key (kbd "<f8>") #'your-ctrl-c-ctrl-c)

    • Nitpick: call-interactively only works on commands which are also functions. So in general you should rather use execute-command which should work for any command, whether it's a function or a key-sequence.

            ASUS Zenbook UX433/UX333 — Configure Touchpad-embedded numpad on Linux

            Image
            0 1 I have an ASUS Zenbook UX433,on which ASUS decided to innovate by embedding a Numpad inside the touchpad (see picture 1). Toggling between classic touchpad mode and numpad (also turns the touchpad LEDs on) can be done through the golden button in the top-right corner of the touchpad. However, on my Manjaro arch Linux config, this behavior does not work by default and I can only use the touchpad, no numpad. Has anyone been able to configure the numpad to work on Linux, or have any idea how this could be achieved? EDIT1: I have had a look at the official Windows drivers for the UX433FA TouchPad, but was not able to make anything of it. I tried installing them on Linux using tools like NDISWrapper, but they do not detect the TouchPad/Numpad hardware, and my understanding of drivers is too limited.
