This can be easily done (by code) writing an action that triggers this
code: if(qApp->focusWidget()) { qApp->focusWidget()->clearFocus(); }

Probably this can be done with a konqueror plugin, but I don't
remember exactly how do they work. Plugins probably can register
actions (which can be assigned shortcuts) so that would be it. You
could then connect the action to a slot that contains the code above.

I like the idea of using applications with the keyboard. When I get
time, I would like to improve the way khtml lets me click in links
using "Ctrl" key which adds a key shortcut for each link, because when
it runs out of letters/numbers it stops adding shortcuts. It should
instead only add shortcuts for links currently visible. Also it fails
in some webpages (like slashdot) by repeating the same shortcut for
different links..

I think in KDE we should try to improve the usability of our
applications with these kind of things. Thanksfully it seems some
people (those working on the simon project for example) are working
towards that.
