Abstract
An apparatus and method of simultaneously pressing different keyboard keys mechanically. The apparatus includes a displacement mechanism that is held by a main carrier that may slide back and forth along an elevated track. The displacement mechanism holds a further track. Further carriers may slide back and forth to desired positions along the further track. Each further carrier holds a rod, whose position relative to the respective further carrier is adjustable. Each rod has an end that constitutes a pressing surface. The displacement mechanism includes a plunger that may be manually pressed against spring bias to lower the further track and thereby the further carriers and the further rods. By doing so, the pressing surfaces of the rods may press against keys of different keyboards that are in alignment beneath the pressing surfaces.
