Complexity: 4

background
The proposed documentation.refactoring contribution point allows extensions to contribute a command that lets users learn more about refactoring

  "contributes": {
    "documentation": {
      "refactoring": [
        {
          "title": "%documentation.refactoring.title%",
          "when": "typescript.isManagedFile",
          "command": "_typescript.learnMoreAboutRefactorings"
        }
      ]
    }

This is rendered at the bottom of the completion list

Testing
Using the code action sample extension, try using creating some documentation.refactoring contributions:

• Can you get the contribution to show up as expected?
• Does the when clause work?
• Make sure that the documentation only shows up when you would expect:
  • It should only show in the lightbulb menu if a refactoring is returned
  • It should always show up in the refactor menu
  • But it should never block keybindings for code actions

I feel it's rather weird that a when clause is necessary. Usually when clauses are optional. Wouldn't a language selector be more appropriate?

I'm not really sure what But it should never block keybindings for code actions means.
