Makes the unused H key a browser back button for better H,J,K,L keyboard navigation
This userscript makes the unused H key into a Back key for better keyboard vim-style navigation.
Because of how it works, after typing G and then H (to go Home), the H key will not work again until any other key is pressed. However, this is not a problem you are likely to come across in use.
