How to move a block or page tab up/down

If you want to change the order of blocks or pages, tap on the Hand icon in the top toolbar.
(If you are working on a mobile phone and want to change the order of the pages, please tap on the Menu button at the top right)
When you are done changing the order of things, tap on the pencil in the top toolbar to go back to Build mode.
