What is this and where to find

[traarrr]

<li><a href="{config.relative_path}/flags?quick=mine">[[flags:filter-quick-mine]]</a></li>

Where can i find the text (or the function it calls) written in double square brackets "[[ ... ]]" .
I would like to edit them or maybe add new

These are called translation strings, you can see that one here https://github.com/NodeBB/NodeBB/blob/master/public/language/en-GB/flags.json#L31. They are translated on transifex https://explore.transifex.com/nodebb/nodebb/
