Is there a way with the advanced editor to hit enter and have it NOT skip a line?

We received this feedback from a customer.

Really would be nice if the advanced editor did not skip a line every time you hit the enter key.

This is presently possible. With the editor if you hold SHIFT and hit ENTER it will move to the next line. The editor uses a hard return (skip a line) with ENTER and a soft return (next line) with a SHIFT + ENTER.
