Where Is The Variables Text?

Hi,

I am making changes to the notifications in Administration > Notifications > Customer Notifications.

The interface is really useful in that a number of variables are given that can be used however - how do I change the text of those variables?

For instance on this line:

{{ snippet("header", { "title" : __("new_shipment_was_created") }) }}

where is the text for "new_shipment_was_created" stored?

I would much rather change the text of the variables than totally change it to use static text.

Thanks!

Administration -> Languages -> Translations

Thank you! I had not understood that this is how the translations section was used!
