This was back in days of X-terminals, so print documents (X11, IDL, Matlab, etc) ran to 1000's of pages bound in multiple thick "books". I tried setting a "left-hand" mode, but because terminals were shared among several users, it was better to train myself to use a right-hand configured mouse so other users could just move the mouse to the right side. Then I broke my left shoulder and had several months with a sling and 9 months of PT. As soon as the sling came off I went back to left-hand mousing because it helped keep the shoulder moving. For the first couple years I had to be diligent about exercising the shoulder to avoid losing range of motion. 30 years later it works as well or better than the one I didn't break. I have helped a number of colleagues work around various injuries. We accumulated an assortment of pointing devices (keyboards with laptop style touchpads, Wacom Bamboo touchpads, trackballs, etc.) for people to test drive, but there were problems finding good device drivers for older devices on the 3 OS's we used most recently (Windows, linux, macOS). It would be nice to have some charitable organization maintain a collection of current pointing devices so they could lend then out to people recovering from injuries and to help people with long-term issues figure out what works for them. The difficulty most people face in finding suitable devices only slows recovery. Hope your recovery continues to progress well. My broken shoulder had a metal bracket with screws and wires for about 6 months while the bone healed, with PT for a total of 9 months. The PT was painful, but I was advised to recover from PT with light exercise (a brisk 20-30 min walk) to keep blood circulating and ending at a good coffee shop. This was effective in reducing pain and maintaining gains from PT. In addition to 1 on 1 PT there was a shoulder clinic with group sessions in a heated pool that was time well spent (I live in Canada, so all this only cost me the price of the coffees). -- George N.
