- Get w3m. I used MacPorts, you can use
brew, it's really up to you. If you're using the former, runsudo port install w3m(assuming, of course, that you've installed MacPorts). - Get
emacs-w3m: RunM-x package-install w3m(or select it fromM-x list-packages)
Unfortunately, Emacs doesn't seem to be very good with dependencies, so before installing w3m you'll also have to manually install mew (I found this in the package repository) and apel (which I had to install the "old-fashioned" way -- get this tarball, then run make and sudo make install ... though if you find a better way please let me know!)
- Now you can run
M-x w3m, and you should see something like this (after navigating to google.com:

Here are a few keyboard shortcuts to get you started:
C-t T => Open a new sessiong => Open URLC-c C-s => Browse open sessionsC-c C-c => Submit formTab => Next link

Enjoy!
