How can I open tslint.json to edit it?

Question

In VScode we often talk about editing configuration files to adapt them to our needs.
But how the heck do you open them to edit them? In particular I would like to open tslint.json to add this line:

"ordered-imports": [true, {
  "import-sources-order": "any",
  "named-imports-order": "case-insensitive"
}]

I would say to click on it, unless I'm missing something in your question.
