Which key expands the selected block to full screen (previously there was an adobe premier tilde)?

Question

Adobe Premiere

Good afternoon! Previously, before CC 2016, there was a tilde hotkey, which expanded the desired block in Adobe Premier to full screen. Now it does not work on SS 2017.
Here is how it worked at 1:50 https://youtu.be/FoZ3OLbM84I?t=110
Tell me where is this key in SS 2017?
Thank you!
