creating a document that automatically redirects to another

I’m sure I’ve read this and maybe even used it some time ago but...

What modx code-snippet can one use in the content of a document if all you need is redirecting to some other docid ??!?

This is for a ’new picture gallery’ announcement, I need the new doc to appear in the rss-feed, but the text it’s just ’go see the gallery’, so the redirect would be more user-friendly.

You can make the document a weblink and point it to any document. Or you can use a snippet to redirect, there is a good one named phiRedirect.
