Translation keys are used to identify a string or text that is displayed to the user. They are used in the translation files to translate the text to the user's language. They are also used in the code to display the text to the user.

Example of a translation key:


Adding translation keys to Tolgee

To add new translation keys to Tolgee, you have a few options:

Creating translation keys manually

To create a new translation key, click the + Add button on the project's Translations view.

Add key button

When adding a new key, you can specify the following options:

  • Key name: The name of the key. This name is used to identify the key in the translation files and in the code. The name must be unique within a project.
  • Namespace: The namespace of the key. This is an optional field that can be used to structure keys into different "buckets" – namespaces separate translation keys to separate files. It can be useful in large projects, we recommend it for projects with more than ~1000 keys. You can learn more on the Namespaces page.
  • Tags: Tags can be used to group keys together. You can select multiple tags. You can learn more on the Tags page.
  • Language text(s): The text that should be displayed to the user in each language. You can specify the text for one or more languages. You can select which languages to show here by selecting them in the dropdown at the top. If you don't specify the text for a language, the key will be marked as "Untranslated" for that language.

Naming conventions

When it comes to naming conventions for translation keys, there are no hard and fast rules. However, it is generally advisable to use naming conventions that are easy to understand and follow a consistent format. Here are some common naming conventions that can be used for translation keys:

  1. Meaningful names: Translation keys should be named based on the meaning or purpose of the content they represent. For example, a translation key for a button that says Save could be named save_button.
  2. Descriptive names: It's also helpful to use descriptive names that provide additional information about the content, such as the location of the content or its function. For example, a translation key for a header that appears on the homepage could be named homepage_header.
  3. Consistent naming: To ensure consistency across translation keys, it's recommended to follow a standard naming convention.
  4. Short and memorable: Translation keys should be short and easy to remember. Avoid using long, complicated names that are difficult to type or remember.

Overall, the most important factor is to choose a naming convention that makes sense for your specific project or organization, and to use it consistently throughout the translation process. This can help to ensure that translation keys are easy to manage and understand, and that translations are accurate and consistent.

Key description

Key descriptions can help translators to understand the context of the key. It's also provided to the Tolgee AI translator to help it understand the key.

You can see the description in the editor directly under the key name.
