How to detect the context when sidebar is focused?

[yangchenyun]

I want to do some key bindings especially when sidebar is focused. The keybind syntax support the `context` keywords, but what's the key to detect the focus of sidebar.

Code: Select all

    { "keys": ["H"], "command": "..." ,
        "context":
        [
            {"key": "side_bar_has_focuse"} // do not work now.
        ]
    },


I know there is a `panel_has_focus` and I am wondering is there something like `side_bar_has_focus` or `window_has_focus`? I read the docs but do not find something similar.
