How to hide toolbar in Eclipse 4.2?

In 4.7.2 you can use the menu items: Window -> Appearance -> Hide Toolbar & Window -> Appearance -> Show Toolbar to toggle toolbar visibility.

> Window > Hide Toolbar

(I'm running 4.2.1.)

Menu was gone but the command seems to be available still now.
Preferences > General > Keys
Type "toggle t" in filter text, then "Toggle Toolbar Visibility" will appear. It seems to work when some key is assigned.
