soft key

(1) A simulated button or keyboard key that is displayed on a touchscreen. Also called a "soft button," "virtual button" or "virtual key," touchscreen soft keys enable smartphones, tablets and remote controls to display any style of user interface. However, they have not entirely made real keys obsolete. A few physical buttons can greatly enhance a touch user interface. See touchscreen and virtual keyboard.

(2) A physical button that serves multiple functions on cellphones and other devices. The button is located next to the screen, which displays the key's purpose at that moment. See virtual keyboard.
