Kab is an address book for use with KDE that lets you save names, postal, email, talk and www addresses, telaphone numbers, important dates and other information in a card index form.
Kab has two basic views, Business Card and Editing. You can switch between them with the View menu.
This view lets you see what information has been stored for each entry in Kab's database
To select a particular entry you can pick it from the Drop Down box in the Toolbar, or you can step through the entries using the large Toolbar arrows or with your keyboard arrow keys.
You can also search the database for a particular entry by using the Edit->Search entries option.
At the top of the main card area you can see the name as it appears in the Toolbar Drop Down box list, and possibly an important date such as the person's Birthday.
An address will be shown in the middle of the card. Kab lets you enter more than one address, for - say - Home, Work and Holiday Dacha. The Drop Down box above the address then lets you select which of these is displayed.
The bottom of the card shows email addresses, URLs and telephone numbers. Left click on the email address to send an email, on the URL to open a browser window. If you have entered more than one email address or URL, then only one will be displayed on the card followed by [..] and when you click on it a little dialog box will appear so that you can choose the address you want.
The File menu has options allowing you to create and use more than one database, import your old KDE 1 address book, print one or all entries, and export the database in HTML format.
