169This transforms the terminal into a tabbar with additional terminals, that
170is, it implements what is commonly refered to as "tabbed terminal". The topmost line
171displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
172button per tab.

174Clicking a button will activate that tab. Pressing Shift-Left and

564All coderefs in this array will be called as methods of the next newly

566gets cleared before the codereferences that were in it are being executed,
