It's a kind of magic...!

Like that queen's song ... understandably my laptop allows me to type the "greater than" and "lesser than" characters again... as well as opening and closing curly braces - that is: { and } ... and even more, I can type ç and Ç (which were with the } key). How has this been possible? Which keys have I pressed to make this work properly again? or has it been an strange phenomenon caused by the storm that hasn't still poured its rain over our heads? I don't know. But it rulez very very much! Now I can code in php and C++ properly!! x)
