The content editor lets you add various types of content including text, images, audio, videos, and more to your site. WordPress is a popular website builder and blogging platform that comes with a robust content editor. We have also updated this guide to add helpful Gutenberg keyboard shortcuts as well. In this article, we will share the most useful WordPress keyboard shortcuts that can help speed up your workflow. If you want to write faster or become more productive in managing your WordPress site, then you need to use these shortcuts. Once you've defined a custom function, you can bind it to a keyboard shortcut if you want.Did you know that there are some really useful WordPress keyboard shortcuts that can save you a lot of time?

This means M-x ( execute-extended-command) lists only the commands that people will probably find useful while working directly with Emacs, skipping internal functions used by code.

If a function does not have the (interactive) keyword, you won't be able to call it with M-x or assign it to a keyboard shortcut, but you will still be able to write Emacs Lisp code that calls the function. (interactive) means that this can be called with M-x ( execute-extended-command) or bound to a keyboard shortcut. Docstrings are optional, but highly recommended. 'Kill from the beginning of the line to point.' is a documentation string (or docstring) that describes what the function does. Since it doesn't contain anything, that means this function does not take arguments. This creates a function called fc/kill-to-beginning-of-line. 'Kill from the beginning of the line to point.' ) because it makes bindings easy to read. There are different ways to specify the key. (There's also LFD and NUL, but you're probably not going to encounter those as often.) You can use angle brackets to refer to some other keys, like, ,. In addition, there are some special characters: RET, SPC, TAB, and ESC must be written in uppercase to mean the special keys they refer to. You can also specify shift by adding S-, so C-X and C-S-x are the same. C-x means Control + x, while C-X is actually Control + Shift + X. Uppercase or lowercase depends on the character in the shortcut. Some people use operating system tools (such as setxkbmap for Linux) to change keys on their keyboard to Super or Hyper in order to enable even more keyboard shortcuts. S- is for Shift, H- is for Hyper, and s- is for Super. C- stands for the Ctrl key, M- stands for the Meta key (which is probably Alt or Option on your keyboard). If you've gone through the Emacs Tutorial ( Help - Emacs Tutorial or C-h t), you'll be familiar with many of the conventions used for writing keyboard shortcuts. For example, setting the keybinding above will result in: You can copy and paste that into your configuration. If you like a keybinding that you've interactively set, use C-x ESC ESC ( repeat-complex-command) to see the Emacs Lisp code for it. After you do that, you should be able to press to save the current buffer. For example, try M-x global-set-key, then press, and assign it to save-buffer. Note that the function must be interactive - that is, it must be something you can call with M-x and it should include (interactive. Type the keyboard shortcut you would like to set, then specify the name of the function you would like Emacs to call. You can use global-set-key interactively by calling it with M-x global-set-key. (Mode maps are set by major modes like emacs-lisp-mode or minor modes like auto-fill-mode.) Setting a global keybinding is usually done with global-set-key, although sometimes you'll see it done with define-key and global-map. You can assign a key to a function globally, which means that it will be available in buffers of any type if there are no mode maps or local keybindings that override it.
