An alternative method to fill in the "Replace With" field is to simply
key-in
Ctrl+L instead... the text cursor will look like it disappeared, but
actually a
Line Feed was inserted and the cursor moved to the end of the second line
(which is located out of view below the bottom of the text box).

I bet you meant ctrl-j, not ctrl-L

I bet you are right. Funny, I tested the keystroke out just before I posted
my message (that is when I noticed the text cursor "disappearing"), so how
did I screw up and type and L for a J? Thanks for catching that.
