Re: sad mac
switching the left and right mouse buttons over.
After my dad got diagnosed with Parkinsons, he ended up having to use his mouse with his left hand[1] since his right hand no longer worked very well.
The first time he asked me to fix his computer after that was (momentarily) somewhat confusing..
[1] He also had to learn to write with his left hand since he no longer had the dexterity in his right hand.
