I suffered from "trigger finger", ring finger of my right hand which I think causes me to hit a key that I don't want. My Laptop also sits on a TV Tray a little high as I sit on an EZ chair. The trigger finger was caused by a nodule just below my finger at the top of the palm. The doctor gave me a very painful shot and it shrunk after a day or two. about a month later, my middle finger on my right hand appeared to have the nodule which also prevents me from making a fist. Thankfully, I can still grip a pistol and shoot it.
As for laptop recommendation, I have a ASUS Vivobook. I do not do any gaming. I have 5Ghz wi-fi thru Spectrum with the senior citizens discount, so only $30/mo. I chose ASUS because they used/still do? make keyboards for many other computer companies. Hope this helps. Good shootin' to ya and STAY SAFE!
