ah the irony of the number of websites that want to tell you how to use w3m, but don't themselves load in w3m because they are totally JS dependant.

How do you open a link in a new tab? meh, you don't really need to, just hit "s" for the buffer selection window which has your whole browsing history.

okay back is shift-b. s to list buffers. esc-e to edit, that seems to be the basics. 

Need to figure out how to save current buffers to file

you can bookmark with esc-a to add esc b to view
