I’m using the OpenGL/Glut library. In the handleKeyPress function, I attempted to display the key that was pressed. To my surprise, the cout is only triggered when the exit key is pressed. So how can I find the number that corresponds to the key? Anyone have a chart?

```auto

void handleKeyPress(unsigned char key, int mouseX, int mouseY) {
	cout << "key: " << key << endl;

	switch (key) {
		// escape
		case 27:
			exit(0);
			break;
	}
}

```
