Tutorial: Viewing an Existing Data File

Start by looking at a sample Personal Knowbase data file:

•	Click on the Open button on the Toolbar.

The Open dialog box is displayed. The existing Personal Knowbase data files are listed.

(If this is the first time you use the Open command, you should be looking at the Personal Knowbase data folder. If not, use the folder listing here to navigate to the Personal Knowbase data folder under your "My Documents" folder.)

•	Double-click on the file name SAMPLE.KNO to open that file.

The Index Window is now the main window on the screen. The keywords from the SAMPLE.KNO data file are displayed in the Index column of this window. The titles of all articles in the data file are displayed in the All Titles column.

Now look at an article from the data file:

•	View an article by selecting its title in the Index Window. Double-click on the first title in the list to open it: Introduction.

The Article Window is now the main window on the screen. The article **Introduction** is displayed in the Article Window. On the first line of the window, the title and the article date are displayed. The keywords assigned to this article are displayed in the column to the right. The text, or content, of the article occupies the majority of the window. The panel across the bottom shows icons for any attachments, in this case a single Internet Address attachment.

Any number of Article Windows may be open at once. You can move to any Article Window or the Index Window by clicking on that window or by selecting the title of the window from the Window menu.

•	Click on the close box in the upper right corner of the Article Window to close the article.

This returns you to the Index Window.

You can locate information of interest in the data file by selecting keywords related to your interest. For example, suppose you are looking for information about computers:

•	Double-click on the keyword computer in the Index column of the Index Window.

The keyword computer is moved to the Selected column of the window. The Titles column changes to the Selected Titles column and lists only the titles of articles related to computers.

You can view any one of these articles by double-clicking on its title as we did above. Then return to the Index Window.

If a large number of article titles are displayed, you may want to pare down the list further by specifying additional keywords. For example, you may want only information about computers and the Internet:

•	Double-click on the keyword Internet in the Index column.

The keyword Internet is added to the Selected column. The Selected Titles column now lists only the titles of articles related to computers and the Internet.

You can view any one of these articles by double-clicking on its title as we did above. Then return to the Index Window.

You can re-expand the list of titles in the Selected Titles column by removing keywords from the Selected keywords list. For example, you may want to see what other information is included about the Internet:

•	To remove the keyword computer from the Selected column, double-click on it.

The keyword computer is now returned to the Index. The Selected Titles column now lists all titles of articles related to the Internet.

•	To view the titles of all articles in the data file, remove all keywords from the Selected column. Double-click on the keyword Internet to remove the last keyword from the Selected column.

The keyword Internet is now returned to the Index. The Titles column now lists All Titles in the data file SAMPLE.KNO.

Internet addresses in article text can be clickable links:

•	Again double-click on the keyword Internet in the Index column of the Index Window.

The keyword Internet returns to the Selected column, and the Selected Titles column lists the titles of related articles.

•	Double-click on the title Web Bookmarks in the Selected Titles column.

The Article Window for the article Web Bookmarks is displayed. Notice that it contains a list of Internet addresses (URLs).

•	Hold the cursor over one of the Internet addresses.

Notice that the cursor changes to the link cursor. This cursor indicates that you have found a clickable link. Such links that are part of an article's text are referred to as "active links".

•	Double-click on the Internet address "https://www.wikipedia.org" to go to this web site.

If you don't want to connect to the Internet at this time, don't click on the link. If you click on the link, your default web browser opens and accesses the site Wikipedia.org.

•	Back in Personal Knowbase, click on the Article Window's close box to close the article.

You return to the Index Window.

Article text can contain hypertext links:

•	Double-click on the title Computer Terms Glossary in the Selected Titles column.

The Article Window for the article Computer Terms Glossary is displayed. In this article, at the end of the definition of the term "ASCII", note the green, underlined text which says "ASCII / ANSI Character Codes". This is a hypertext link. Hypertext links can link to files, URLs, or other Knowbase articles.

•	Double-click on the green, underlined text to open the Knowbase article which this hypertext link points to.

The Article Window for the article ASCII / ANSI Character Codes is displayed.

•	Click on the windows' close boxes to close the 2 open articles and return to the Index Window.
