select unmarked

Just as there is the ability to select all marked items, the inverse would also be nice to have. It would save ALOT of time when you are dealing with very large marked lists. I know you can select marked and then drag from top to bottom to get the unmarked, but this goes VERY slow when you have alot of marked entries on a site and in memory.

Shift+Ctrl+S to select marked, followed by Ctrl+I to invert selection.

As DayCuts pointed out this can be done as a two step process, though I don't see any reason not to make this a feature, perhaps "select unmarked" would be good to have.

I'll put this on my to-do list.
