The controlID of the current hot control.
The hot control is one that is temporarily active. When the user mousedown's on a button, it becomes hot.
No other controls are allowed to respond to mouse events while some other control is hot.
once the user mouseup's, the control sets hotControl to 0 in order to indicate that other controls can now respond to user input.
// Click on the button to see the id
function OnGUI() { GUILayout.Button("Press Me!"); Debug.Log("id: " + GUIUtility.hotControl); }
