I changed my mind and I agree with you and John that this change makes sense.

There was a recent change made to a number of scrollable views (ListView, TreeView, TableView, TreeTableView) to add alt-ctrl-LEFT/RIGHT/UP/DOWN (option-command-LEFT/RIGHT/UP/DOWN) key bindings just for that.

Perhaps we could apply the same idea to the ScrollPane.
