Start a numbered list from any number using the syntax “N. [@N] ⋯”, a nice way to have 0-numbered lists or lists with text in between that does not reset the numbering.

• Emacs CheatSheet

  M-n 𝕏 / C-u n 𝕏

  Repeat command 𝕏 $n$ times.

  • n may be omitted in the second form, defaulting to 4.
  • Whence, it may be stacked: “C-u ⋯ C-u 𝕏” repeats command 𝕏 4ⁿ-times where n is the number of C-u commands.
  • Holding Alt key and press 1 then 2 then 3 then release the Alt key, and, say, press the j key. Now you have 123 j’s inserted lol.

I have so many things installed, I’m forgetting some of the stuff that I installed to be more productive! Whence this “personal” cheat sheet. —I’m not trying to be comprehensive; see the existing cheatsheets for Emacs and Org.

Below are the bindings that are shipped with Emacs or the packages one installs. To be somewhat useful to others, my personal bindings will be “enclosed” in quotes. I will write X,Y-x,y to denote one of X or Y followed by one of x or y; e.g., C,M-d denotes C-d and M-d –for character and word deletion, respectively. Hopefully this makes it easier to group related commands.

As always, since I’ve installed which-key, it suffices to press a prefix then look at the resulting menu 😃

In nearly every Emacs application, press

?, h

Obtain help; see listing of possible commands.

q

Quit current application, closing buffer.

Use Emacs in any text area on my OS with Cmd Shift e.

Using C-x 5 ... in place of C-x ... operates on the ‘frame’ level –i.e., other Emacs GUI instances. C-x 4 ? is for acting on the other window, where ? = f, d, b for finding file, directory, buffer. Perhaps most useful is C-x 4 c for working with different parts of the same buffer.

C-x 4 c clone-indirect-buffer-other-window. It splits the current window, clones the current buffer and visits the clone in the newly opened window.

C-x 2 splits and copies the current buffer, but it’s inappropriate for looking at one part of the buffer while working on another part since every editing change happens live, including superficial visual changes such as region folding and narrowing. Instead, we select the region we’re working on, for example, then press C-x 4 c C-x n n to clone the buffer then to narrow the region we’re working on.

All commands are prefixed by C-x x; main commands:

{{{no-vertical-padding(1.5)}}}

• C-x u Visualise undo tree.
  • t, d toggle timestamps and diff display.
  • M-{,} Go to previous, next branching point.
  • q Exit at currently selected state.
• C-x r u Save current buffer state.
• C-x r U Restore saved buffer state.

Save & restore is useful for experimenting with a function definition, for example.

By default C-t is transpose characters; I’m using it quickly open a terminal.

Org-mode: All commands are prefixed by C-c.

Using the “super key” to navigate between org blocks.

Then,

Delete an article by moving it to ‘Trash’.

This allows us to “zoom in” or “focus” on a particular region; the rest of the buffer is ‘hidden’. All commands begin with C-x n.

C-c C-e during a search to make live edits.
