I was following the tutorial on turtlesim in wiki.ros.org/ROS/Tutorials/UnderstandingTopics, the steps 1 and 2 work fine, but when I execute the command of the step 3 and i start to use the arrow keys, it didn't move the turtle

What happens when you run rqt_graph in another terminal? It should look like this:
(node) /teleop_turtle -> (topic) /turtle1/cmd_vel -> (node) /turtlesim

By the way: you must have the terminal selected (as though you can type in it) when pressing the arrow keys.

Great, it works, but I have removed all ROS files, and reinstalled them, it was because of other problems during the installation that I haven't noticed during the process. Thanks a lot :)
