What does the proposed API look like?

How should this be implemented in your opinion?

Text customized by locales: $themeLocaleConfig.openNewWindowText

Are you willing to work on this yourself?

Yes

@ktquez - so since we already have the outbound link indicator, would you just want us to add the alt text of the users specification (via $themeLocaleConfig.openNewWindowText) ?

[ktquez]

Yes it can be.

@ktquez - this PR should address this issue

#2603

@ktquez - I don't see the comment, mind re-commenting on the PR for me?

[ktquez]

Sorry @d-pollard
Done.
