'''Dasher''' is an [[input method]] and [[computer accessibility]] tool which enables users to compose text without using a [[Computer keyboard|keyboard]], by entering text on a screen with a [[pointing device]] such as a [[Mouse (computing)|mouse]], [[touch screen]], or mice operated by the foot or head. Such instruments could serve as [[prosthetic devices]] for disabled people who cannot use standard keyboards, or where the use of one is impractical.<ref>{{Cite journal | last1 = Wills | first1 = S.
