How to switch text case in visual studio code

How does one switch the case of highlighted text in Visual Studio Code? VS allows this via CTRL+SHIFT+U and CTRL+U.

Is there a command binding that I can set up to do this, or is it by default some other key combination?

Echoing justanotherdev's comment:

Mind-blowing and useful:

1. Command Palette: CTRL + SHIFT + p (Mac: CMD + SHIFT + p)
2. type >transform pick upper/lower case and press enter

I've written a Visual Studio Code extension for changing case (not only upper case, many other options): https://github.com/wmaurer/vscode-change-case

To map the upper case command to a keybinding (e.g. Ctrl+T U), click File -> Preferences -> Keyboard shortcuts, and insert the following into the json config:

{
  "key": "ctrl+t u",
  "command": "extension.changeCase.upper",
  "when": "editorTextFocus"
}

EDIT:

With the November 2016 (release notes) update of VSCode, there is built-in support for converting to upper case and lower case via the commands editor.action.transformToUppercase and editor.action.transformToLowercase. These don't have default keybindings.

The change-case extension is still useful for other text transformations, e.g. camelCase, PascalCase, snake-case, etc.
