Over on planetkde.org (and on some KDE mailing lists) there is a bunch of discussion about web browsers and KDE. A common theme was that rather then talking about KHTML v.s. Webkit it you should just get out there and code. In that spirit I finished off my AccessKey branch and merged it in tonight. When you press the ctrl key little semi transparent boxes will appear all over the screen highlighting links. If you type the letter in the box that link will be followed. Using this it is much easier to browse without a mouse, not to mention faster. This was a feature that I really enjoyed using in Konqueror and missed.
Unfortunately it uses the new QtWebKit dom API (which will be in Qt 4.6) so it is only enabled if you are using the Qt master git branch or linking to QtWebKit Trunk.
