Riddle me this - Mac keyboard strange issue

[cashmax]

My left shift key works fine
My letter O key works fine
But together, they do not work, I don't get a capital O, in fact I get nothing. All works fine with the right shift key and all the other letters work fine with the left shift key.

I have rebooted the Mac, in fact I installed a new Mac OS (clean install) and the problem still exists???

New keyboard?

[Jenny Tailor]

System preferences - Keyboard - Shortcuts - Restore to default.

Keyboard set to GB

After that - I'm out of ideas.

Mine starts doing similar when the battery is getting low ... what's the charge like on it (assuming its the wireless 'board)?

Mine did this after I cleaned it with a wet wipe that was too wet..

Bought this as a replacement which is great!

(there are a lot of mac-a-like keyboards on amazon but I chose this for the large Enter key).
