I (and I'm sure others) would really benefit from more keyboard shortcuts!
Specifically, for giving online lectures I'd love to switch between a screenshare of my slides and "content from second camera" (to get a large hi-res video image of me speaking) at the push of a button (I'd use that shortcut with StreamDeck to make it even simpler).
There is no good reason why I should need to buy an expensive third-party software like ZoomOSC just for this simple functionality.
I do know about the share screen shortcut, but there I then need to select a particular screen with my mouse so it doesn't work at the push of a button. This could easily be solved by a shortcut that automatically shares either the first window, or if I select a window at the start of the Zoom session that it would automatically re-open that one. And of course a short-cut that directly opens the second camera content.
