If you did the tutorial you know how. Use the arrow keys to move. Up moves you forward, down moves you back, left makes you turn left and right makes you turn right. Click on the speech bubble at the top left corner of the screen to talk. You can select what you want to say. If you told Wizard 101 that you were 16 or older than you can type what you want to say. Hit enter, type what you want to say and then hit enter again to say it. Words in red mean that you cannot say that word or it is misspelled. Hope this answers your questions. You should probably do the tutorial again for more.
