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
Altkey and press1then2then3then release theAltkey, and, say, press thejkey. 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.
There are already cheatsheets for Emacs, Org, and even Elisp; so why bother with another one? The general ones are great but contain stuff I rarely use, such as information on registers, but are missing stuff I’d like to know, such as Helm keybindings which are not shipped with Emacs.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 😃
C-h C-h | Help for the help command |
C-h h | Learn how to say ‘hello’ |

C-x 2,3 | Split window above, to the side |
C-x o | Switch cursour to other window |
C-x ^ | Increase window height |
C-x {,} | Shrink, widen window |
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.
“s-<arrow>” | Jump to window via arrow key |
“M-<tab>” | Flip to next buffer |

All commands are prefixed by C-x x; main commands:
s | Select a space to go to or create it. |

Save & restore is useful for experimenting with a function definition, for example.
Undo Tree also has functions which save an undo state to a register and which restore a save state from a register. These are bound to C-x r u and C-x r U by default. These are great for things like experimenting with a function definition.{{{no-vertical-padding(2)}}}
