How to put the at sign "@" on my PC / LAPTOP

Just press the <Alt> "Alternate" key and types the # 64, it is one of the form.
Another way is presionano the <alt> key on the right side of the space bar + the letter "Q".
If you then does not come out the same <alt> and the number "2" from the top of the keyboard.

You can also select the "@" give copy and then paste. Greetings.
