Intercept the Ctrl+Alt+PgUp/Down for a report page

Browse Source 
With the focus on the webkit webview, this key sequence can be used to
scroll the view. For the key sequence to work for tab page switching a
callback is connected to the 'key-press-event' for the webkit view and
checked for the sequence and passed to the notebook if required.
