How to move a tab back to the parent Window in Safari 5.0?

Question

I dragged a new tab out to create a window. Now how do I re-merge it with the previous window?

There seems to be no way of doing it. (Except create a new dummy tab, drag this one to the previous window, close the window with the dummy tab).

Answer 1

Hit Ctrl-Shift-T to always show the tab bar, then you can drag the tabs between windows.
