Version: (using KDE 4.4.2) Installed from: Ubuntu Packages Accesskeys are a common method to assign focus on an element (http://www.w3.org/TR/html401/interact/forms.html#adef-accesskey). I filed the bug first for Rekonq, but they said it's a kdewebkit issue. More info at bug #229120 (https://bugs.kde.org/show_bug.cgi?id=229120)
Yes, this is a known missing functionality that has been added to the ISSUES file at http://websvn.kde.org/trunk/KDE/kdelibs/kdewebkit/ISSUES?view=markup but it is something that should be implemented upstream in QtWebKit itself. If someone upstream does not implement this, I will see if I can do the patch for upstream myself at some point in the future...
*** Bug 262975 has been marked as a duplicate of this bug. ***
Reminder to myself: port this functionality from kwebkitpart: http://commits.kde.org/kwebkitpart/e26fc12c3afe4f2576934b8dffd7edea08f7e257.
KDEWebkit got deprecated/removed.
