Slider phone
Extracted from the Wikipedia article Slider (mobile phones).
Slider is a general term of a form factor in mobile phones composed of usually two, but sometimes more, sections that slide past each other on rails. Most slider phones have a display segment which houses the device's screen, while another segment contains the keypad or keyboard and slides out for use. The goal of a sliding form factor is to allow the operator to take advantage of full physical keyboards or keypads, without sacrificing portability, by retracting them into the phone when they are not in use.
