Hotkeys

Use keyboard shortcuts, or hotkeys, to improve your labeling performance.

View out-of-the-box hotkeys

From the labeling editor, click the settings icon to see more details about hotkeys or to enable or disable hotkeys.

Use the <Shortcut> tag

Use the Shortcut tag to allow annotators to insert a predefined text snippet into their current annotation.

They can do this by either clicking the shortcut button or by pressing its hotkey.

For example, use the following to insert predefined text into a text area:

<View>
  <Image name="image" value="$captioning"/>
  <Header value="Describe the image:"/>
  <TextArea name="caption" toName="image">
    <!-- Inserts “CAR” when clicked or on Ctrl+1 -->
    <Shortcut alias="Car" value="CAR" hotkey="ctrl+1" background="#333333"/>
    <!-- Inserts “AIRPLANE” when clicked or on Ctrl+2 -->
    <Shortcut alias="Airplane"   value="AIRPLANE"   hotkey="ctrl+2" background="#FFEE00"/>
  </TextArea>
</View>

Customize global hotkeys from your account page

You can easily customize global hotkeys on from the Account & Settings > Hotkeys page.

Customize global hotkeys using environment variables

If you want to change the hotkeys used for specific actions, set the EDITOR_KEYMAP environment variable with valid JSON in your .env file or when starting Label Studio. For example, to change the keyboard shortcut used to submit an annotation to shift + s, set the environment variable as follows:

EDITOR_KEYMAP='{"annotation:submit":{"key": "shift+s","description": "My Custom Submit Hotkey!"}}'

This overwrites the existing hotkey mapping with your custom mapping. See more about how to set environment variables.

Refer to the full list of customizable hotkeys in the keymap.json file to update a different hotkey combination.

You cannot use this environment variable to remove an existing or add a new keyboard shortcut.
