How do I not proceed to next unread article?

[google]

Hi--

I like to keep lots of ticked messages around for reference. Sometimes
I go through and unmark the ones that I don't need any more. When I
hit "d" on those (in the summary buffer or the article buffer), gnus
jumps to the next unread message, which could be hundreds of messages
away from the bunch I'm working on. So how do I make gnus not jump to
the next unread message after
hittin "d"?

  --thanks for any clues
