I have solved this for now using this Javascript triggered to start at timeline of the slide:
document.querySelector('.acc-textinput').addEventListener('keyup', () => {
if (event.key === 'Enter') {
document.querySelector('.acc-textinput').blur();
var player=GetPlayer();
var _journal=player.GetVar("journal");
player.SetVar("journal",_journal + ""+ "\n" + "\n");
document.querySelector('.acc-textinput').focus();
}});
It's looking for the Enter key being pressed in the .acc-textinput CSS selector i.e. the text entry box.
When the Enter key is pressed it blurs (unfocuses) the text box hence updating the text input variable, in this case journal.
It grabs the variable adds the break characters, moves the cursor down and refocuses the box. The input can then be continued.
The break characters will show in the text box but not the print out.
Only caveat is that Articulate keep using the same CSS selector.
Thanks to Gavin Elliot for starting me off with the correct selector.
hmmm the post is deleting the html br characters. Can someone tell me how to embed a code snippet into a post...
