Voice dictation is too tedious for web surfing, so I’d stick with a keyboard. Although I have no suggestions how to overcome arthritis, I do have two suggestions that might improve your typing accuracy.
1) Consider an oversized keyboard. I Googled “large keyboard” and this is just one example:

2) Consider a standard size keyboard that has better tactile feedback. The modern, cheap keyboards have a indistinct, mushy feel. I like the old-style “clickety-click” keyboards such as IBM made 30 years ago. I tried a SIIG keyboard at a local store and just loved it. That keyboard is constructed with an aluminum base and feels hefty and solid. The keys have a crisp, quality feel. I can type better with something like that.

Thanks. I did a lot of looking today, among which was this type .
But i think what i need is a kb with soft touch, fairly raised and spaced keys. Below is one that looks the best for the price, but reviews (Amazon, Newegg) do not say all i would like to know. Pray and press. Digital Innovations Easy-View Keyboard #4250400
