 * @see {@link doc:context Verb, Noun}
 * @description Takes key and returns string
 *
 * Sometimes it's not an option to use an attribute (e.g. when you want to annotate an attribute value).
 * There's a `translate` filter available for this purpose.

 * ```html
 * <input type="text" placeholder="{{'Username'|translate}}" />
 * ```
 * This filter does not support plural strings.
 *
 * You may want to use {@link guide:custom-annotations custom annotations} to avoid using the `translate` filter all the time. * Is
