In vscode, how to define a shortcut to invoke a custom snippet for current active language?

Question

Let's say I have a Ruby user snippet to output the string ruby and a Python user snippet to output the string python. How can I make Ctrl+b to invoke the aforementioned Ruby snippet when in ruby-mode, and invoke the Python snippet when in python-mode?

Answer 1

{
    "key": "ctrl+b",
    "command": "editor.action.insertSnippet",
    "args": {
        "snippet": "ruby"
    },
    "when": "editorLangId == ruby"
},
{
    "key": "ctrl+b",
    "command": "editor.action.insertSnippet",
    "args": {
        "snippet": "python"
    },
    "when": "editorLangId == python"
},

Also, instead of using the snippet argument value to define your snippet inline, you can reference an existing snippet by using the langId and name arguments.
