Hello,

 

I want to be able to have a modifier key (like shift) held down and have a specific action taken beside the normal onRightClick function that items have.  I have been looking for a key press detector and I am not sure if there was one built into minecraft or forge itself.  Any help would be appreciated and if extra information is need I will provide what I can.

In your base class:

public void keyPressed(KeyEvent e) {
    int keyCode = e.getKeyCode();
    switch( keyCode ) { 
        case KeyEvent.VK_a:
            boolean isOn = true; 
            break;
        case KeyEvent.VK_b:
            boolean isOn = false; 
            break;
     }
}
