When using a reference field, you can hover over the reference icon to view the referenced record as a popover. A few people already know, if you don’t want the popup to disappear as soon as you move your mouse, just pressing the shift key will keep it in place allowing you to scroll.
That one’s been doing the round for a while now, but today a colleague showed me another cool thing with the shift key in Fuji.
From a list view, you can hover over the (i) icon on the row to view the full page form. Holding shift before hovering over the icon will actually render the page fully editable, UI actions and all! Saves a click into the record to update it.
