Automating toolbar clicking

I'm new to AutoIt and am going through the tutorials.
I've gone through the automate notepad example and its clear about opening notepad sending text to it, closing and saving.

But what I'm not clear about is how do I go about automating clicking on the toolbar (the line having "file edit format view help" and its submenus.  When I hover the finder tool of "AutoIt Window Info" program over the toolbar of notepad containing "file edit format view help" I don't get any information back.  Can someone give me a simple example of automating some clicks of this toolbar and also tell me how I get information about the toolbar such as control names etc.

Thanks,
Harry
