Nothing new here; this has been available for a while and mentioned in forums before, but it doesn't seem to be widely known. I was just documenting this today, so I thought I would share it as a Moodle tip - with thanks to Tim Hunt for jogging my memory on Twitter.
Being able to move activities and resources by dragging them to their new location is a great feature:
However, you can find yourself trying to do tricky two-handed manoeuvres if your item is at the bottom of a long course page and you need to move it right up to the top, dragging and scrolling at the same time.
Instead, just click on the move icon - usually a cross-hairs icon as (1) below. This then displays a screen where you will see links to all the items on your page and the tops of sections (2). Just click to select the location you want to move your item to and the job is done. No dragging or scrolling
