Guys, hello to everyone.
This is my first day with my macbook. I am completely new about mac's and apple. I am using microsoft, xp more than 8 years, I used to it and today is one of my worst days.
I opened my macbook, try to understand and learn it. Try to find keyboad short cuts. for example I do not know how to open right click menu with my macbook mighty mouse (I also bought a mighty mouse, luckly ı can connect ıt)
I try to watch apple movie trailers from apple's web site. I opened trailer's web page and opened a trailer. I try to make quicktime full screen, I tried to find a way to open right click menu. and I used every keyboard key. when ı was doing it ı did not look keyboard, mybe ı pushed command key 3 times, or option key, maybe some combinations, ı did not remember, ı was just tryint to open right click menu.
and now, macbook's keybord has gone. when on safari's adres bar, I can not write anything. ı am very upset now, ı can not find any way to open keyboard again. which combination has locked it, and which will open it?
in microsoft, there is no such things, they told me that apple is better than it, but in my first day it is a great disaster.
please help me to open my keyboard again, and open right click menu, and how can ı make a quictime video full screen, please help.

Open the keyboard system preference and go through the settings to make sure everything looks ok - and you can learn from looking at it rather than doing random things. Then go to the International system preference and set the languages that you want to use, etc.
