# Document and Row Labeling
## Overview
The **Document labeling** and **Row labeling** extensions display the question sets configured during project creation, allowing users to answer questions for each row or document.
{% tabs %}
{% tab title="Row labeling" %}
Row labeling extension
{% endtab %}
{% tab title="Document labeling" %}
Document labeling extension
{% endtab %}
{% endtabs %}
## Question set modification
You can manage and update question sets either from the **Label management** page in your workspace or directly within a project. This includes adding new question sets, editing existing ones or removing them. Learn more about [label set management](/workspace-management/label-management/label-set-management.md).
Within a project, question sets can be modified from the three-dot menu in the extension.
### Upload a new question set
You can add or replace a question set in two ways:
* **From the three-dot menu.**
* **Using the file uploader** (only shown only when no question set is configured).
### Use existing question set
This option lets you select a saved question set from the library. Using a different question set will:
* Replace the current question set.
* Remove existing answers associated with the previous set.
### Edit question set
You can modify question sets even after the project has started. You can add new questions, edit existing ones, or remove them.
{% hint style="info" %}
Changes made inside a project do not automatically update the corresponding question set in the **Label management** page.
{% endhint %}
#### Add questions
Click the add icon to add a new question to the current question set.
#### Edit question
Select the question you want to modify and update its settings as needed. You can update both display-related properties and functional behavior:
* **Display-related properties**:
* Question name.
* Slider color.
* Date/time format.
* Other visual properties.
* **Question type**: Change the question to a different type.
* Switching between **Text** and **Text area** keeps existing answers.
* Switching to any other question type removes previous answers.
* **Required or optional:** Choose whether the question must be answered or can be skipped. If existing answers no longer match the updated setting, labelers will be asked to review them.
* **Single or multiple answers**: Change whether the question allows one answer only or multiple answers. If existing answers no longer match the updated setting, labelers will be asked to review them.
* **Answer options**: Add, rename, or delete options.
* Adding options gives labelers more choices.
* Renaming options updates only the displayed text and keeps existing answers.
* Deleting options removes answers associated with those options.
* **Regex validation**: Add or update regex rules to validate text input. If existing answers no longer match the updated setting, labelers will be asked to review them.
* **Slider range**: Update the minimum or maximum slider value. Answers outside the updated range will display a warning in the labeling extension.
* **Remove questions:** You can remove both newly added and existing questions when needed.
Questions that have already been submitted have the following limitations:
* They cannot be removed or reordered.
* Dynamic question sets cannot be modified.
### Save to library
Save the current question set to your library (**Label management** page) so it can be reused in other projects.
## Keyboard shortcuts
### Disable keyboard shortcut
This option disables numeric keyboard shortcuts for selecting answers.
If this option is disabled, **Match shortcuts to numeric labels in dropdowns** will also be disabled.
### Match shortcuts to numeric labels in dropdowns
This option makes dropdown shortcuts use the same numeric values as the dropdown options. For example:
| Dropdown option | Default shortcut | Match shortcuts enabled |
| --------------- | ---------------- | ----------------------- |
| **0** | Shortcut 1 | Shortcut 0 |
| **1** | Shortcut 2 | Shortcut 1 |
| **4** | Shortcut 3 | Shortcut 4 |
{% tabs %}
{% tab title="Disabled" %}
Shortcuts don't match the numeric labels
{% endtab %}
{% tab title="Enabled" %}
Shortcuts match the numeric labels
{% endtab %}
{% endtabs %}
This option only works when:
* The project contains at least one dropdown question.
* Keyboard shortcuts are enabled.
* All dropdown options are single-digit numbers between 0 and 9.
* If any dropdown option is not a number between 0 and 9, this feature will not apply.
## Discard draft from current document
This option removes any unsaved or unsubmitted changes in the current document. Use it when you want to discard your current progress and start again.
