You can look in the header file. GLUT has a function for getting the status of some keys like ctrl. I think the name is glutGetModifier.

Arrow keys and keys like Page Down/Page Up/Home/End are handled in a different function that normal keyboard commands. Ordinarily, keys like 'a' and 'b' would be directed to the function you provide in the glutKeyboardFunc(...) function, they're going to go to the function in the glutSpecialFunc(...) command.

For example, here's how I handled that problem...

  void keyboard2GL(int key, int x, int y){	if(key == GLUT_KEY_LEFT) xdir -= 2.0f / zoom;	else if(key == GLUT_KEY_RIGHT) xdir += 2.0f / zoom;	else if(key == GLUT_KEY_DOWN) ydir -= 2.0f / zoom;	else if(key == GLUT_KEY_UP) ydir += 2.0f / zoom;	else if(key == GLUT_KEY_HOME) {xdir -= 2.0f / zoom;	ydir += 2.0f / zoom;}	else if(key == GLUT_KEY_END)  {xdir -= 2.0f / zoom;	ydir -= 2.0f / zoom;}	else if(key == GLUT_KEY_PAGE_UP)    {xdir += 2.0f / zoom;	ydir += 2.0f / zoom;}	else if(key == GLUT_KEY_PAGE_DOWN)  {xdir += 2.0f / zoom;	ydir -= 2.0f / zoom;}}void createWindow(void* arg){	// Code goes here...	glutKeyboardFunc(keyboardGL);	glutSpecialFunc(keyboard2GL);	// More code goes here...	glutMainLoop();}   

Hope this helps! :D
