Enter a very long command at shell. Now continue to up-arrow into history, tweak it, and make it a lot longer. At some point you're thinking: "I should have made this a multi-line command when I started". Well, now that the command is all just one line, is there a way to break it up?
foo | grep "aaaaaaaaaaaaaaaaaa" | grep "bbbbbbbbbbbbbb" | more
Now to make that easier to continue editing:
foo |\ << enter some control character here to split the line grep "aaaaaaaaaaaaaaaaaa" |\ grep "bbbbbbbbbbbbbb" |\ more

Is there an easier way to break up a long line of multiple commands in the terminal?
