The text line (with line number) in Emacs, is called
logical line . When a logical
line gets too long in typing window, Emacs provides two distinguish solutions:
line truncation and
line wrapping .
Here is the link of technicalities of the solutions:

• The breaked or wrapped line is refered as
screen line, as opposed to
logical line. Why do we care the
differences? To precisely control the keybinding navigation between lines.
• Although the default line setting in Emacs is
wrapping on, you may want to
check your local setting with
C-h m to see which exactly major/minor-mode
you’re using before rushing in trying other settings.
• If you’re using
j(or k) to navigate between lines, check which function it is binded
evil-next-line moves between logical lines. Conventionally this binds to
evil-mode and VIM.
evil-next-visual-line moves between screen lines. Conventionally this binds to
• Note most other line operation commands act on
logical lines, NOT screen
lines. For instance,
C-k kills a
• If making MS office word instances:
truncate off and
text-mode are like violent justified on both sides;
auto-fill-paragraph are like left alighned.
• I personally use
auto-fill-paragraph with self-setting fill-column to write
M-q to arrange lines as I needed. It’s neatly fast, coz other automated
indentation rules are quite complicated and therefore slows your computer.
This may help you decide your configuration: !(/img/line operation 2.jpg)
• This code can rearrange wrapped lines to long logical lines：
;; unfill paragraph: the opposite of fill-paragraph (defun y:unfill-paragraph-or-region (&optional region) "Takes a multi-line paragraph and makes it into a single line of text." (interactive (progn (barf-if-buffer-read-only) '(t))) (let ((fill-column (point-max)) ;; This would override `fill-column' if it's an integer. (emacs-lisp-docstring-fill-column t)) (fill-paragraph nil region))) (define-key global-map "\M-Q" 'y:unfill-paragraph-or-region)
