Toshiba's Tecra series of laptop computers offers a wide variety of models that can run several different versions of Windows. The function keys are standardised across the models, making them the easiest way to enable and disable your touchpad no matter what model you use. Toshiba's Tecra series is designed to allow easy, high-speed multitasking for professional applications. The touchpad is part of this functionality, but some users find it more convenient to disable the touchpad while typing or to turn it off permanently and use an external mouse for navigation.
