hds live: how to switch splitscreen to fullscreen?

[til]

Finally I'm a proud owner of an hds-live.
Still learning how to use it best for my purposes. One of the first things I wanted to do is to go fullscreen from my splitscreen and back again.
So I googled and found a video which explains it nicely, but for the carbon, where you can apparently long-press the panel key.
But the live doesn't have a panel key. How would it work on the live?

Only works on the 12 & 16 with the programmable shortcut keys as far as I know

Check page 29 of the users manual. It tells you how to set Quick Access keys. On the 7 and 9, the pages button long press will be the quick access, on the 12 and 16, there are 4 buttons that can be programmed.
