How to make "tab" and "shift-tab" switch the selection in command palette ?

[Dangerise]

I want to bind my "tab" to act like "down" and bind my " shift-tab" to act like "up" , so that I can move the selection by "tab" and "shift-tab" in the command palette or a file finder

How to do that ?

I found what to do!

    {
        "bindings": {
            "shift-tab": "menu::SelectPrev",
            "tab": "menu::SelectNext",
        }
    },

Just this (no context) works for me
