Emacs W3m

May 20th, 2013

This year I switched from vim to emacs. The reason is quite simple, I want to try different things, that’s all.
Emacs is a highly configurable editor that you can use it to read emails, chat on irc, read pdf files, or
whatever you can imagine. One of the most useful plugin is using emacs-w3m
