Recognizing Building Blocks

Learning a subject becomes easy when you recognize the building blocks or basic units of the subject.

Let us take one example from our everyday working. We use so many different software. It can be a word processor ,spread sheet, database or a specialised application of any subject. In all these software we find basic units called menu on menu bar. The following list describes some standard menus you will find on many menu bars.

File : This menu contains any functions related to whole files used by your program. Some of the typical menu items are : new, open , close, save, save as, print and exit.

Edit : This menu contains the functions related to editing of text and using the windows clipboard. Some typical edit menu items are : undo, cut, copy, paste, clear , find and replace.

View :The view menu allows different looks for the same document. A word processor for example , might include a normal view for editing text and a page-layout view for positioning document elements, as well as variety of zoom options.

Tools : This menu is the place for your program’s utilities or helper functions. For example a spelling checker, grammar checker might be included for a word processor.

Windows: This menu allows simultaneous editing of different documents databases or files. The window menu lets users arrange open documents or switch rapidly between them.

Help : The help menu contains access to your program’s help system. Typically it includes menu items for a help index(a table of contents for help), a search option(to let the user quickly find a particular topic).
