window.itemClicker can be set to do nontrivial handling of links. Like opening in a new window. Look at [[http://www.uzbl.org/wiki/michaelraskin#config|MichaelRaskin config]].

You can also set window.uzbl_digitSymbols to use some ten symbols as digits in link choice.

/* This is the basic linkfollowing script.
 * Michael Raskin: added customization of action on
 * click.
 * Its pretty stable, only using numbers to navigate.
 *
 * TODO: Some pages mess around a lot with the zIndex which
 * lets some hints in the background.
 * TODO: Some positions are not calculated correctly (mostly
 * because of uber-fancy-designed-webpages. Basic HTML and CSS
 * works good)
 * TODO: Still some links can't be followed/unexpected things
 * happen. Blame some freaky webdesigners.
