In 11.04, I was able to select a file in Nautilus and while dragging/folding the file change workspace using the regualr keyboard shortcut keys.

This was very handy if for example I had to attach a from folder I had been working in -- simply start dragging, change to the workspace where I was composing an email and then drop.

This does not work under 11.10. If I hold a file, I am no longer able to change workspace. The keyboard shortcuts simply have no effect.

Is there some way I can regain the described behavior?
