Movieclip not moving on its own - actionscript-3

Question

I have a game. (Feel to download it here)
In my game, you may notice that the man doesn't move on its own. You have to click the screen once to get the man to move left and right with the arrow keys.
My Main.as:

This is the file I use to make the man move. Where is the code do I change to make the game work so the man moves the after "Go!", and you don't have to click the screen.
Another question I have is: When you press "P", you can pause the game. However, you may notice after unpausing the game by pressing "P" again, the timer is off by the number of seconds you were paused. This code also is the code for the timer. What do I change in the code to make the timer run correctly, meaning that after unpausing the game, it doesn't skip the number of the seconds you were paused, instead it continues from where it left off.

Answer 1

This is getting too long a comment thread for this question. After you call buttonClickHandler4, your keyboard events should be functioning.
Set debug points, or trace statements, to see if buttonClickHandler4 is being called. Add the same to make sure downKey and move are being called. This should narrow down the problem.

Answer 2

EDIT: I figured out the problem using this link: http://www.trainingtutorials101.com/2010/10/keyboard-events-wont-work-unless-user.html
I had to use the command stage.focus = this to focus the stage on my movieclip man, so that way it could listen for keyboard events without my mouse clicking the screen.
And to remove the yellow rectangle around the man I used the command stage.stageFocusRect = false.
Thanks to #dhc and #Vesper for all of their help.
