Emacs tips

• To get more color themes for emacs install the emacs-color-themes, available in most major distros. In ubuntu:
  sudo apt-get install emacs-color-themes
  My current favorite is clarity. One you find one you like, edit your .emacs file (in your home directory) and add the line:
  (color-theme-clarity)
  (replacing “clarity” with your theme of choice, natch)
• Once you know the keyboard commands, the toolbars just get in the way and take up valuable screen real-estate. Add the following lines to your .emacs file to get rid of them:
  (tool-bar-mode 0)
(menu-bar-mode 0)
• The scroll bar is also annoying, as are emacs’ default scrolling methods. We can hide the scrollbar by adding this line to our .emacs file:
  (scroll-bar-mode nil)
  The following lines will also add mousewheel support:

  
;; Mousewheel
(defun sd-mousewheel-scroll-up (event)
“Scroll window under mouse up by five lines.”
(interactive “e”)
(let ((current-window (selected-window)))
(unwind-protect
(progn
(select-window (posn-window (event-start event)))
(scroll-up 5))
(select-window current-window))))
(defun sd-mousewheel-scroll-down (event)
“Scroll window under mouse down by five lines.”
(interactive “e”)
(let ((current-window (selected-window)))
(unwind-protect
(progn
(select-window (posn-window (event-start event)))
(scroll-down 5))

  (select-window current-window))))
(global-set-key (kbd ““) ’sd-mousewheel-scroll-up)
(global-set-key (kbd ““)
’sd-mousewheel-scroll-down


Happy Hacking!
