Thanks for your confirmation that it does work, Tokinsom. That set me to figuring out why it didn't work for me.
After puzzling and playing around, I realised that I was simply entering '"Xxx" & NewLine & "Yyy"' as the text string in the Text object Properties and that whatever you enter there simply displays literally.
What I needed to do was use a 'Set text' event to display my text string and then I got my newline working.
Another beginner's lesson learnt!
