Insert page break keyboard shortcut

Working in Pages v6.3, it would be so much quicker if I knew what the keyboard symbol for Insert Page Break was...I know the Command key, but the symbol that looks like an up-arrow with a line across the top (see the image I've attached) - I have NO idea which key that is, and I have tried them all on my Apple keyboard. Which key is that?? Your insight is so very much appreciated!
