Certain keys support variables for translations.
These variables are replaced with actual values calculated during product operation.

If a key supports variables, they are displayed under the **Custom translation** field.
Click the variable to include it in the translation.
Each variable can be included only once.

Alternatively, the variables can be omitted to use a less detailed message.

## Example [#example]

The keys on the picture below support variables.
When the message is displayed in the WebUI, the variables are replaced with the actual links.
