Language aware keybinding

[ze-gois]

I am working with scripts - prototyping.

I am used to MATLAB and Jupyter keybindings.

To insert a cell we usually hit "ctrl+shift+-".

I am to reach the same effect in Zed.

Chatting with Claude Sonnet I was induced to insert to ~/.config/zed/keymap.json:

 {
    "context": "Editor & languageId == 'python'",
    "bindings": {
      "ctrl-shift--": ["insertText", { "text": "\n## %% Cell\n" }]
    }
  },
  {
    "context": "Editor & languageId == 'rust'",
    "bindings": {
      "ctrl-shift--": ["insertText", { "text": "\n// %% Cell\n" }]
    }
  },

However it does not work.

Any advices?

I think & should be && in your example?
