Keycommnad for zoom audio content?

On the right side there is a zoom for audio content zooming, how do I do that from a command?

Do you mean vertical zooming with Shift-H, Shift-G?

No, they zoom the channels, they are the one on the lower right corner. There is a other one on the opposite site of the scrollbar on the top, that is the one.

Depends on what view you’re in, it zooms the Audio if you’re editing Audio.

No Key Command for what I think you’re referring to.
