Question

What are the must know shortcuts in Xcode for faster application development?

As a special interest, the Mac shortcut I want to know is the one to open application menus (File, Edit, View, Project, Build etc.,). In Windows, if we type Alt + F, the File menu will drop down, and we can navigate through the sub-menus using the arrow keys or typing the letters that are underlined in the menus. How can we do something like that in Mac?

Thanks..
