Setup

Clone: https://github.com/re5et/.emacs.d-for-my-friends.git to your home directory

mv ~/.emacs.d ~/.emacs.d.backup
git clone https://github.com/re5et/.emacs.d-for-my-friends.git ~/.emacs.d

Start Emacs

you should be presented with this README and you can continue from there.

Max OSX stuff:

use alt as meta

Ctrl-H v (describe variable) mac-command-modifier RET Use customize to set value as meta

Keybindings

Emacs has a lot of keybindings, many of them useful. We aren’t going to discuss defaults, you should use the tutorial (C-h T) for that.

This will be a list of things that are different or added.

Overridden Defaults

C-j is remapped to C-x

C-x is too clumsy a keybinding for as important as it is in Emacs. Anytime you hit C-j, it will generate a C-x for you.

Anywhere you see C-x, you can use C-j instead.

C-j is originally mapped to `electric-newline-and-maybe-indent` and will usually be bound to RET by the mode you are using.

M-j is used as a user prefix key

M-j is a nice prefix key (usually user prefixes are C-c, which is less ideal).

M-j is originally bound to `indent-new-comment-line`, which isn’t that useful.

Project Navigation

For our practical purposes, projects are directory structues that have a .git folder at the top level. You can get much fancier with project defenition, see here: https://github.com/re5et/simp

M-j g	magit status buffer
M-j f	fuzzy find file
M-j s	search project
M-j S-s	search entire project
M-j d	project root dired (directory listing)

Bookmark Prefixed Project Navigation

To pick a project from a bookmark and then take a project navigation action, you hold down Meta for the second keystroke

M-j M-g	magit status buffer
M-j M-f	fuzzy find file
M-j M-s	search project
M-j M-d	project root dired (directory listing)

Frame and window movement

M-l	next-in-frame-window
M-L	next-multiframe-window
M-h	previous-in-frame-window
M-H	previous-multiframe-window
C-S-,	Undo window configuration change
C-S-.	Redo window configuration change
C-S-\	Rotate windows
M-S-\	Swap split orientation
C-S-b	move back one in window history
C-S-f	move forward one in window history

Buffer niceities

C-,	indent entire buffer according to mode
C-S-/	revert buffer (to last save)
M-j G	git time machine for buffer file
C-x C-k	kill focused buffer

Editing niceities

M-z	delete from point up until characater
M-o	indent-and-open-newline
C-o	previous-indent-and-open-newline
M-S-b	backward to word
M-S-f	forward to word
M-S-m	expand region
M-S-n	duplicate current line down
M-S-p	duplicate current line up
C-S-m	multiple cursors “mark all like this”
C-S-n	move current line down
C-S-p	move current line up
C-S-y	insert from kill ring search
C-S-s	search forward for thing at point
C-S-r	search backward for thing at point
C-S-space	exchange mark and point
C-x f	fill region (wrap region)
C-x C-s	overridden save that forces save each time
M-j S-m	rename buffer and file
M-j k	copy line
M-j M-k	kill whole line

Jumping around

M-j J	bookmark-jump
C-x C-b	ibuffer (instead of list buffers)
C-x C-d	dired-jump (go to directory for file)
