Wow Mike, I had no idea that so many options existed. Thank you sincerely.

Now, the question becomes; which option will make onscreen keyboarding easiest for me? Since I have two separate applications, desktop (which I run from across the room) and my Dynavox which is mounted on my power wheelchair which has a touch screen, I hope to cover both with a single pointing device.

Its no longer easy for me to mentally envision the ramifications of compound schemes and I used to do that easily all day long before my stroke. Now I need help in planning my breakfast due to the several food options. Add the fact that on Tuesday and Thursday the options change. My solution has become...eat what's brought, the same liquidy scrambled eggs every morning for three years straight without complaint. Oatmeal and cappuccino is keeping me alive. You don't know what I'd give for one fried egg, sunny side up, with a piece of toast. The tiny pleasures I always took for granted.
