I have an iMac which is about 3 or 4 years old now, it has the standard wireless keyboard which has now started having problems. For some reason "Shift + o" doesn't work (wierd, because shift everything else works and o works and "Caps Lock O" works.). More problematic is the right cursor key, which, once touched, auto repeats madly making it difficult to do quite a lot of stuff. Anyway, I'm too stingy to buy a real Apple replacement, so I bought one of these: http://tinyurl.com/k7q9qsk Now I fully accept I've bought a piece of crap, but perhaps someone can help. : It has no escape key. My son plays Minecraft and he is bleating about this as it is a major funtional key in Minecraft, bringing up the menu, etc.). It has a key at top left which has a rounded corner square on it, no idea what that's for. So, question is, is there a way to map ESC to this key or another function key?
