Wrong QKeySequence::NextChild on OS X

On OS X:
QKeySequence::NextChild is, among others, associated with Qt::CTRL | Qt::Key_Tab

But in Snow Leopard (I did not check Leopard), this shortcut is a system-wide shortcut to switch between applications.

On another hand, Qt::META | Qt::Key_Tab is used eg. in Safari to switch from tab to tab. I guess this is what you should do in Qt too.

Same remark for QKeySequence::PreviousChild
