detect when 'comma' is pressed in GLUT

I have "glutKeyboardFunc (keyboard);" in my main function, How I can detect when user press 'comma' or full-stop. I want to move (strafe) to your left in the XZ plane a distance when comma is pressed. and move to right in the XZ plane when full-stop is pressed. The current code does not response. 

 if(key==GLUT_KEY_UP)
{
  eyez = eyez + RUN_SPEED;
}
else if(key==GLUT_KEY_DOWN)
{
  eyez = eyez - RUN_SPEED;
}
else if(key==',')
{
  eyex = eyex - RUN_SPEED;
}
else if(key=='.')
{
  eyex = eyex - RUN_SPEED;
}

What you need here, dear fellow UoM student enrolled in COMP27112, is the ASCII codes for comma and dot.

That is 44 and 46 respectively.

case 44:
  // Comma
  break;
case 46:
  // Dot
  break;

The glutKeyboardFunc() callback is only for ASCII-type keys. I'm surprised you are getting arrow key events from it.

Create a glutSpecialFunc() callback for non-ASCII keys.
