Shortcuts to switch between panes/windows?

First, thanks for a great app, and detailed and thoughtful answers to issues!

Apologize if I overlooked something basic in iPad or a-shell docs but: How do you switch between panes (Split View) or a-shell windows using shortcuts only? The following all assumes hardware keyboard.

As an aside, If I do Cmd-N I get a new split window but focus stays in the current pane. Not sure if that’s the most sensible option.

I feel like option-tab sometimes works to switch between panes but mostly a-shell just loses focus. With two windows I don’t know of a shortcut, other than standard iPad touch options. I’m looking for something like Vim or Tmux shortcuts whether in Split View or full screen/multiple windows. IPad touch options work fine.

Thanks!
