how to remove 1 page perminantly

How do you remove 1 delete page perminantly without empting the total trashbin?

I don't think you can. You would need to go into the database and delete the resource there, but that's not really recommended.

I rarely actually delete resources; I simply unpublish them, empty their fields except for something like "extra" in the pagetitle field, and re-use them later instead of creating a new resource.
