<a href="http://www.abilitynet.org.uk">Ability Net</a> is a charity that do
free assessments of individuals [1] - letting you try out various bits of
kit, giving advice, etc.

As a first step, you might look at some of their factsheets about keyboard
shortcuts, slowing down the mouse, etc. (Keyboard shortcuts are very useful
- if you can avoid using the mouse, you don't have to worry about any
problems you might have using one.)

They assessed me at work and instead of the 15 minutes I can use a normal
keyboard and mouse before my wrists and fingers become painful, the
keyboard and mouse they recommended mean I can use them all day without
problems.

John - I have tried mice of various kinds, and tracker balls, over
about 25 years. Personally I find a thumb operated tracker like the
Logitech cordless trackman wheel the best, but must stress that people
will differ a lot in their personal preferences. Although you may
choose one for regular use, it is as well to have one or two
alternatives to use when the joints revolt.

I also have RA in hands/wrists. and find that of those currently available (the best one I
ever used is now no longer available), the Kensington Expert Mouse is best. Have a look at
it here:

Although it's called a mouse, it's actually a trackball, which I find easy to use on bad
days with my palm or heel of my hand. You can program all the buttons, which can be
invaluable for much used software, and can have different configurations for: bad days,
medium days, good days ;-)

Hope this is of some help.

I'd recommend speech-recognition, but considering what a useless
dweeb you are here on USENET, I can't imagine you having the skill
or patience to help someone use it.
