	* You must open the Intuition library ~~before~~ ~~you can use~~ the Intuition ~~functions.~~ ~~Certain~~ ~~languages~~ ~~such~~ ~~as C require the pointer to~~ the Intuition ~~library to be assigned to a variable called IntuitionBase (see Chapter 1 for more about this)~~.		* You must open the Intuition library and get the Intuition interface before you can use the Intuition functions.
	* When you set up a window, you also specify the events that you want to know about. If the user performs some activity that triggers one of the events you specified, Intuition signals you and sends a message. The message is a pointer to an IntuiMessage data structure that describes the event in more detail. Messages about Intuition events are sent to a MsgPort structure which queues up the messages for you in a linked list so that you may respond to them at your convenience.		* When you set up a window, you also specify the events that you want to know about.

	Workbench, together with Preferences, gives the user an easy way to control the OS and launch applications. These programs are built with the same Intuition tools available to application programmers giving the whole Amiga system an integrated look and feel.
