keyboard shortcut to create the "Go Full Screen" icon

I'm not entirely sure I understood what you meant by "creating the button." The Go Full Screen button is already available in the top menu bar. It is the second icon from the right. Starting with the Adobe Connect 12.10 release, this button is only visible when accessing rooms through a browser. It has been removed from the desktop application because the view there is already maximized by default.

Individual pods also offer a fullscreen option. Hosts can control whether participants can use this feature by going to Preferences > General > Allow participants to view pods in fullscreen. This setting is useful when hosts want participants to focus on the entire layout. Sometimes if participants take a pod fullscren, they might miss out on what is happening in other pods.

Below is a screenshot showing the fullscreen button, both in the top bar and within a pod (Video pod in this case).

There is no dedicated shortcut for fullscreen within Adobe Connect. However, browser shortcuts can be used for the same purpose. For example, pressing F11 in Chrome will take the room fullscreen, which is equivalent to using the fullscreen button in the top bar.
