• Usage

1. Load phscroll.el (require 'phscroll)
2. Select a region you want to horizontal scroll
3. M-x phscroll-region

Other commands:

• M-x phscroll-delete-all : Delete all scrolling area in the current buffer
• M-x phscroll-delete-at : Delete a scrolling area at point
• M-x phscroll-update-at : Update (redraw) a scrolling area at point

The following keys are available in scrolling area:

• C-x < (M-x phscroll-scroll-left)
• C-x > (M-x phscroll-scroll-right)
• C-l (M-x phscroll-recenter-top-bottom)
• C-S-l (M-x phscroll-recenter-left-right)

• In org-mode

The following elisp enables horizontal scrolling in table parts of org-mode documents. By setting org-startup-truncated to nil, other parts will be displayed in wrapping.

#+begin_src emacs-lisp (setq org-startup-truncated nil) (load "org-phscroll.el") #+end_src

Tips:

• To turn off the effect of phscroll, use M-x org-phscroll-mode.
• To scroll the current position of the screen to the left edge, press C-S-l twice.
