vim commands on tabs that are not files

Is your feature request related to a problem? Please describe.
It's annoying when I can't use my vim hotkeys on certain tabs that are not files. For example when I search for an extension and double click it, I would like to be able to close it using :q. Another example is when using the Julia extension and I plot something, it opens up a plot gallery tab. I like to put this in a vertical split with my code on one side and the plot gallery on the other. I would like to be able to use :q or <C-w> to quit or switch between my code and the plot gallery tab.

Describe the solution you'd like
Is there a way to do this? I tried setting something like below but it didn't work. Perhaps it's more complex?
{ "key": "ctrl+w", "command": "extension.vim_ctrl+w", "when": "jlplotpaneFocus" } ]

Start with the VS Code keybinding configuration and trace the extension.vim_ctrl+w command under the jlplotpaneFocus context. Check how :q and <C-w> are dispatched for non-file tabs such as extension search results and Julia plot galleries; done means those Vim actions can close or navigate those tabs without disrupting file tabs.
