Emacs - How can I find the name of a command (to invoke Mx <command>) for key binding?

In Emacs, the command names are as follows:

  • indent everything inside the buffer (depending on which language you use) (equivalent to selecting the entire buffer and click on the tab)

  • move through the paragraph (equivalent to ctrl-up and ctrl-down)

  • move by word (equivalent to ctrl-right and ctrl-left)

The truth is that I switched to a macbook for a professional level, and these functions are not possible due to binding OS shortcuts to ctrl + ...

I already tried to find this on google, but no results. I will assign new bindings to these functions in .emacs.

To help you help: Ch k describes the key. Just hit it and then a key combination and then it will give you a name and a document for the related elisp function.

For you this:

  • indent-region (usually it depends on the mode)

  • forward paragraph and inverse paragraph

  • reverse word and forward word

  • Mx indent-region
  • Mx backward-paragraph and Mx forward-paragraph
  • Mx backward-word and Mx forward-word

As already mentioned, you can use Ch k to display the documentation for this binding. Another useful command is apropos-command tied to Ch a to find if you know part of its name.

But another really cool feature for text alignment is align-regexp associated with Cx \ .

eg.

 a = 12; baz_to_bar = 3.14; foo = 42;

Select a region and then use Cx \ = RET

 a = 12; baz_to_bar = 3.14; foo = 42;

And as its name suggests, you can use a regular expression to determine how emacs align your text. Enjoy it!
