TrackWrite

Nicknamed the "Butterfly keyboard," it was a laptop keyboard from IBM introduced in 1995 on its ThinkPad 701C. When closed, the keyboard split apart and one part folded under the other enough to fit the smaller footprint of the case. When opened, it expanded to a full-size keyboard. See ThinkPad and TrackPoint.

Considered one of the finest examples of mechanical engineering on a portable computer, the TrackWrite lifted up and spread open to a full- size keyboard beyond the footprint of the laptop. (Image courtesy of Craig Leres, www.xse.com/leres)

Apple says the Macbook Pros come with the second generation of the butterfly keyboard that the company debuted on its Macbook lines in 2015.
Despite keeping the form factor of the MacBook Pro, it is quite easy to spot the new iteration from its predecessors due to its upgraded display that has richer and more vibrant colors, a massive Force Touch trackpad, an upgraded keyboard that is almost identical to the Butterfly keyboard of the 12-inch MacBook, all-new speakers and the new marvel in Apple's advanced technologies, the Touch Bar.
