# How to use validation marks

Validation marks are used to indicate which subtitles or dubbing have been validated. This makes it easy for you to go back over the project and get an idea of the percentage of video that has been checked in each language.

Validation mark is specific to the language and the type of project (subtitling or dubbing).

So the sentences validated for subtitling and dubbing may be different.

### Automatic validation on reading

During video playback, phrases are automatically validated.

If you click on the mark and leave a red cross state then only a manual action will change the status of the phrase. This means that even if you play the video, the status will not change automatically.

### Percentage of validation by language and project type

Each time a subtitle or a dubbing is check we update the pourcentage of the language review.

### Right-click action

If you right-click on the mark you have several bulk actions available.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.checksub.com/get-started/quick-start/how-to-use-validation-marks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
