If you reached here from this video, please see the version tagged demo.

Requirements

Emacs 26 and up! (Due to helm, 25 and up; due to a auto-complete dependency, 26 and up!.)

Installation

Drop the init.el in your ~/.emacs.d/ and (re)start emacs.

Emacs will download use-package and then the required packages. This should take a few minutes. Restart emacs.

Features

• Melpa added
• Packages: use-package, tabbar-mode, ace-window, auto-complete, helm, goto-chg
• C-x bindings not listed below are bound to nil: In case some exists that is missing below, it is a bug; report them! Known issue is C-x 8- key bindings which I've been unable to disable.
• global auto-complete-mode, electric-pair-mode, show-paren-mode, auto-revert-mode, visual-line-mode, linum-mode, column-number-mode, helm-mode
• Slower scroll

Usage Intention

• Use intended when you are limited to a terminal interface and want a more-or-less familiar interface. The presence of terminal can mess up several keys, for instance C-g and <backspace> become equivalent (unless there's a workaround I do not know of!). Another being the response of scroll, forcing the existence of some key bindings for scrolling; with that case, why not keep the default one?
• Why not complete default? Because the default binding of C-z would frustrate the new user. There are several other keys.
• If you have access to a full GUI emacs and do not want to learn emacs, take a look at emacs-modern branch.
• If you are using emacs to learn Common Lisp and want to delay learning emacs, take a look at
  • slime-company-modern if you have access to GUI emacs
  • slime-company if you do not have access to GUI emacs and are stuck to a terminal-only. This intends to keep the bindings of the master branch, and augment them with lisp specific bindings.

Key-bindings

Text Editing

• C-a: Select all
• C-s [std]: Search (forward); because changing this means changing several other maps and we don't want to go "too far" from vanilla emacs, so that you get used to it as well
• C-r: Replace (forward); because see C-h next
• C-h (Backspace): Delete word to the left - this is so because on the terminal backspace and C-h are equivalent. And I haven't searched enough for a workaround.
• C-z: Undo - in emacs, redo is undo of undo; this also avoids loss of redo-undo "trees"
• C-<space> [std]: enter/exit text-selection mode
• C-w [std]: Cut; because C-x is complicated
• C-y [std]: Paste; because
• C-v [std]: Scroll down
• M-v [std]: Scroll up
• C-g [std]: Cancel command
• C-k [std]: Cut line this point forward
• M-k: Delete line this point forward
• C-/: Un/comment-line; also works for un/commenting region when selected
• C-l: Goto line

• M-S-/: Move line (selected region) up or down
• C-M-s: Forward search symbol at point
• C-M-r: Forward replace symbol at point
• M-q: Quit emacs (with prompt)
• C-.: Goto last change (useful when one scrolls)
• C-,: Goto last change reverse

Window and Buffer Management

• F7: Split window horizontally: "" is more memorable, but its bound to something in some terminals

• F8: Split window vertically - two parts of the "8"

• F9: Expand window vertically

• F11 [std]: Toggle "frame" full screen

• S-F11: Delete other windows (this, to avoid accidentally pressing "" while trying to go full screen)

• C-o [~std]: Switch window

• M-o: Switch buffer

• C-t: Open *scratch* buffer

• C-S-t: Reopen closed file

• C-<tab> / C-S-<tab>: Switch tabs

• M-x [std]: arbitrary commands (helm-M-x)

• C-x C-f [std]: Open file (helm-find-files)

• C-x C-s [std]: Save file

• C-x C-d [~std]: Open directory. Press '?' for help. (dired)

• C-x C-w: Close file (kill-this-buffer)

• C-x C-r: Rename file (and buffer)

• C-x C-k: Delete this window

Miscellaneous

• M-h k: Help key

• M-h v: Help variable

• M-h f: Help function

• M-m: ansi-term switch between line and char modes

• M-n: ansi-term next command

• M-p: ansi-term previous command
