Vim like key-bindings to change focus between widgets ?

[JackTheMico]

Since users can create complicated layout with GridView, It would be convinent if there are key-bindings like Vim to use "h,j,k,l" to change focus on widgets.

For example, I want to create a email TUI, I would put some email accounts in top bar and some mailboxes of each account in sidebar.
It would be great if I can change focus between widgets by pressing "Tab" or "shift+Tab" or "ctrl+h,j,k,l",
and then use "h,j,k,l" in each widget to select different mailboxes or accounts or emails.

My guess is this would be a good idea because there are bunch of people like using vim or emacs and that's including myself😃.
So what do you think?

Not involved with dev, but it would make sense to have an abstract tab order resolver that a given application could implement rather than hard-coding a particular set of behaviours + keybinds.

I would be really interested in this.
