Writing a formula on different lines?

Is there a way to put parts of a formula (while writing or editing it) on separate lines, like in a visual editor, to better organize? It works when I cut and paste, but I can’t figure out how to do it in the box.
Any suggestions?

In other words, how would I put this in to the editor, without cutting and pasting?:

     "Alphabet","Alphabet (NASDAQ:GOOG)"),
     "Microsoft","Microsoft (NASDAQ:MSFT)"),
     "Amazon","Amazon (NASDAQ:AMZN)"),
     "Facebook","Facebook (NASDAQ:FB)")
