Uzbl is a lightweight webkit browser following the UNIX philosophy - to do one thing and do it well. Features Uzbl uses the WebKit layout engine, and therefore inherits support for many web standards, including HTML, XML, XPath, CSS, ECMAScript (JavaScript), DOM, and SVG, passing the Acid3 browser test. Webkit supports Netscape-style plugins such as Adobe Flash Player and MPlayer. Numbered links feature enabled for keyboard navigation Uzbl's design focuses on keyboard control and hotkeys, although Uzbl supports mouse and other pointing device input. Like the pentadactyl and vimperator Firefox extensions, Uzbl employs a mode-based interface derived from the vi and Vim text editors. Rather than move the cursor to an address bar or a link, a user presses a hotkey to switch to "command" mode. From this mode she may: select links in the viewport through assigned keys (0 through 9 by default) or through typing an unambiguous string of the link text; navigate to another web page by typing its URL; modify settings; and perform other normal web-browsing tasks. While this mode-based interface creates an initially-steep learning curve, once learned it typically allows a user greater speed and convenience than many other browsers. Uzbl allows configuration of the hotkeys used.
