Ket is a minimalist, immersive algebra editor for the keyboard literate.

This program is provided for people who regularly perform not-too-specialized algebra at or around a computer. The program takes time to learn, but will, in time, provide a fast and efficient method to manipulate algebra. Additionally, Ket is able to teach by providing a different and more immersive environment in which a user may experiment with algebra from a new perspective.

Ket maintains a list of equations that summarize the algebraic steps as one or more initial equations are transformed into one or more results. Each equation is modelled as a collection of symbols that are connected together in some way. This collection is a `tree' of arguments, each subbranch of which is a function of functions and arguments.
