Indenting multilines/block with vscode and vim plugin

Question

Un-indenting lines in VS Code is already on the site, but it doesn't work for me. I'm not 100% sure the answer can be adapted to my situation (the question asks about Vim "mode"). If it is, the context for the accepted answer isn't obvious to me.

I assume we're supposed to splice the JSON fragment

{
  "key": "shift+tab",
  "command": "outdent",
  "when": "editorTextFocus && !editorReadonly && !editorTabMovesFocus"
}

into our settings but it's not clear how or where. The app has a settings.json, a keybindings.json and the plugin has package.json.

Ctrl+[ and Ctrl+] aren't functional for me. Presumably they would be without the Vim plugin, but the plugin overrides the Ctrl commands.

Answer 1

Just as in normal vim, typing >> and << in normal mode or > and < in visual mode will indent and un-indent lines, respectively.
