Is there a file of the key bindings used by the emacs/w3m mode?

I am a keysnail newbie and just installed keysnail and added the HoK and Tanything plugins?

Do these commands already in exist?

 - Open in new tab

 - Close current tab

- Browser forward button

- Browser back button

Is there a file with the Emacs/w3m bindings which can be added to the keysnail.js?
