A character input system for a limited keyboard, in which a number of input keys in the keyboard is smaller than a number of characters in an input alphabet, the system comprising: a memory comprising a plurality of different mappings of said characters onto combinations of said keys; and a selector for allowing a user to select one of said mappings for character input. The different mappings are optimized for different users and different purposes, so that the user may select a mapping for simplicity of use, or one optimized for touch-typing, or for minimal key pressing or for minimal ambiguity or for other factors and combinations thereof.
