Dasher is an information-efficient text-entry interface, driven by natural continuous pointing gestures. Dasher is a competitive text-entry system wherever a full-size keyboard cannot be used - for example on a palmtop or wearable computer, or when operating a computer one-handed (by joystick, touchscreen or mouse) or zero-handed (i.e. by head-mouse or eyetracker). This document describes version 4.2.0 of Dasher.

Dasher can be started by selecting Dasher from the Accessibility submenu of the Main Menu, or by running the command dasher on the command line.
