Some XF86 keys are undefined in Qt

Some XF86 keys are undefined in Qt, meaning that doing

void widget::keyPressEvent(QKeyEvent* ev)

{ QKeySequence seq(ev->key()); qDebug() << seq.toString(); }

will result in strange output. For instance the output of the XF86WWW key is

"Meta+Ctrl+Alt+Shift+�"

while it should really be something like

"WWW"
