The right arrow key started to fail about a week ago, and now the command key as well. It's like they're "lower" and don't give feedback, if that makes sense. As a result, it either fails entirely (nothing happens when pressed) or feels "weird". It get get unstuck after a while, if I press the key hard several times. Also, it doesn't always happen. I thought it could be due to heating issue but the machine doesn't get that hot ? At least compared to previous mac. Hmmf, one more thing to add to the long list of disappointments with this machine.
