- `ui:$path` where `$path` is either `/basicui/app?...` for navigating sitemaps (using the native renderer) or `/some/absolute/path` for navigating (using the web view).
- `ui:$commandItemSyntax` where `$commandItemSyntax` is the same syntax as used for the [UI Command Item]({{base}}/mainui/about.html#ui-command-item).
- `http:` or `https:`: Opens the fully qualified URL in an embedded browser on the device.
-- `rule`: Runs a rule by using the following syntax: `rule:$ruleId:$prop1Key=$prop1Value,$prop2Key=$prop2Value,...` where `$ruleId` is the id of the rule, and optional properties to send to the rule are in the format `name=value` separated by commas. Most rules can omit the properties.
-- `app`: Launches a native app when possible using the following syntax: `app:android=$appId,ios=$appId:$path` where `$appId` on Android is a qualified app id like `com.acme.app` (see [partial list of Android ids](https://github.com/petarov/google-android-app-ids)), and on iOS is the registered URL scheme along with an optional `$path` like `acme://foo` (see [partial list of iOS ids](https://github.com/bhagyas/app-urls)). Either `android` or `ios` can be omitted if that platform is not used.
