Jarte Word Processor

Jarte is on the face of it simple and no more automated than is strictly necessary, but there's a lot of very neat tricks under the hood. The freeware version is very feature rich, upgraded to the full paid version which is cheap and you can use it on all the household's PCs with a single licence.

Its "clickless" interface can be helpful to someone with limited hand function.
