Hi. 
 
	Is there any way to cancel a built construction or a unit in progress from the build icons on the right of the screen?
 
	 
 
	I effectively froze a game the other night by accidentally building a power turbine when I had no power station. All other controls were idol and all I could do was abort the game!
 
	I can’t find any keyboard shortcuts for this online and can’t remember from playing as a kid if it’s even possible. 
 
	I’m using a Mac but all other shortcuts are the same as windows.
