Mac Pro 3.1 aluminum keyboard, the control option key combo on left side of key board does not work
On Apple Mac Pro 3.1 aluminum keyboard, the control option key combo on left side of key board does not work. Work around is to use control option on right side.
Left control with right option works but not all the time. The left option key is dead. Left command key works all the time.
In a test of all keys, the = sign above num pad 8 does not work. Can't say that I ever tried it before.
Be happy to hear/see if there is some magic cleaner/trick that might fix this?
