https://translatewiki.net/w/i.php?title=MediaWiki:Go/da&action=edit states that it "Appears next to the search button. Goes directly to the page with that name, if it exists."
Please explain what is still left unclear.
Thanks, that text is entirely clear and needs no further clarification.
Weird, I didn't see that text when I was translating using the interface https://translatewiki.net/wiki/Special:Translate?action=proofread&group=mediawiki&language=da&filter=translated. I was looking for it, otherwise I wouldn't have requested more information. But I must have missed it somehow, scrolling up and down in the little pane. But now when I go back, I can see the text.
The given link to https://translatewiki.net/wiki/MediaWiki:Go/da, where the description is more visible, was inserted automatically, so I didn't visit that page.
Sorry for the inconvenience.
