This problem is resolved by inserting the following code to the
TocWidget.cpp file
void TocWidget::keyPressEvent(QKeyEvent *event)
{
if(event->key() == Qt::Key_Return)
{
QModelIndex const & curIdx = tocTV->currentIndex();
goTo(curIdx);
gui_view_.setFocus();
gui_view_.activateWindow();
}
}
Will be pushing a fix to the branch soon.
