Thank you so much for this extension. I've been using pentadactyl for years until support for it eventually stopped. After that I tried a host of others such as saka-keys, vimfx etc. eventually settling on vimium; but none of these did the job the way pentadactyl used to. While Tridactyl may be missing a few features I got used to such as page marks and regex search, it seems to be much faster than I remember pentadactyl used to be, and its documentation is far neater and easier to browse. In my opinion, it's currently the best vim-like extension out there.
