In elinks, ‘g’ is used for an empty “go to” prompt, and ‘G’ is used for
prompt populated with the current URL.  In many other places, ‘o’ and
‘O’ are used (“open”), respectively.  These places would be the firefox
addons vimperator or pentadactyl, and a number of keyboard driven webkit
browsers, though this is because they are vim-oriented so g/G are
already used.  I think the ‘o’ ‘O’ mnemonic is nice as well, and these keys
are free in eww.
