Questions about MetaTrader 4

 

I just started using MetaTrader 4. So, I have a couple of questions. 

 

I accidentally clicked out of one the 4 charts that are in the program, and I'm trying to see how to get it back. I don't remember what it was. Is there some refresh button or something?

 

Also, how do I input my broker account for trading?
