    Desktop Panel

    The KDE desktop panel (kpanel) is situated along the bottom of the screen. It provides quick, point and click access to:

    Application Starter

    To launch the application starter click on the large K on the panel. A selection of sub menus will be made available.

    Window List

    To select the Window List click on the icon that looks like a layer of windows. This produces a list of all the applications you currently have open on each of your desktops. If the application is held in parenthesis this indicates that the application is iconified. Click on an application to access it.

    Home Directory

    All your files are kept in your home directory. To view this directory in KDE select the house icon on your control panel. A window will appear on your desktop containing all the files and directories contained in your home directory. To view the contents of a directory or a file click once on the icon you wish to view.

    KDE Control Center

    The KDE Control Center (KControl) provides an easy way to access all the configuration modules e.g. fonts, colour, background window configuration etc.

    Find Utility

    Kfind is KDE's find utility. Its aim is to help you find files within directory hiearchies.

    Utilities

    The utilities folder can be selected by clicking on the icon resembling a tool box on the panel. It contains utilities such as the address book, calculator and terminal.

    Logging Out and Locking the Screen

    The padlock icon will lock your screen if you need to be away from your workstation for a few minutes. To unlock the screen you must enter your password. The icon above that looks like the letter x will log you out of your KDE session.

    Virtual Desktops

    There are four desktops, labelled one, two, three and four on your panel. Click on the appropriate number to move between desktops.

    XEmacs

    XEmacs is a powerful text editor, for more information on XEmacs read the introduction to XEmacs in the CS1 guide

    KWrite

    Kwrite is KDE's own text editor. It is also a powerful editor but does not at present support printing. KWrite's main feature is the fact that it has coloured syntax for many programming languages such as C/C++, Java, Perl, HTML and many more.

    Newsreader

    The newsreader under KDE is called KRN. To start KRN click on the KRN icon on the desktop panel. You will now be presented with the groups window. When you choose a newsgroup to open (either by double clicking on the newsgroup or by selecting Newsgroup | Open) you will be presented with the articles window. To read an article click on that article. Articles with a green dot beside them are unread, after you have selected that article it will be marked with a read dot. To delete messages use Options | Expunge. You can choose whether to expunge Read, Unread, Current, Tagged or All messages by using the drop down menu on the left hand side of the articles window.

    Mail Notification

    The mail notification utility for KDE is KBiff. To use KBiff click on the blue mailbox icon on the panel and select OK. You will now have a mailbox docked in the bottom right hand corner of the desktop panel. When you have new mail you will be notified by a bleep sound and the presence of an envelope in your mailbox. Click on the mailbox to receive new mail.

    KDE Help

    Help on KDE applications is available by clicking the blue book on the desktop panel.

    Notepad

    KNotes is KDE's notes application. Notes can be printed, mailed, set as an alarm, will recognise URLs and display a calender. To open a KNote click on the yellow pad on the Desktop panel. A blank note will appear, to view the options available with KNote right click the mouse over the KNote window.

    Double clicking on a URL in KNotes will open that URL in a kfm browser window.

    Files can be drag and dropped from the Desktop or kfm on to KNotes.

    The alarm can be set by right clicking over the KNote and selecting Operations | Alarm. The KNote will sound a couple of bleeps and appear on the date and time you specified. KNotes can be also be cleared, saved, deleted and renamed from the Operations menu.

    Terminal

    The terminal emulation for KDE is kvt. To open a kvt terminal select the monitors icon on the Desktop panel.

    E-Mail

    KDE's mailer is Kmail, for information on Kmail go to the Email section in the CS1 guide or select the KDE help icon on the Desktop panel.

    K File Manager

    kfm is the K file manager and is used to view directories and files on your Linux file system. To open a kfm window choose the Application Starter then Home Directory or select the Home Directory icon on the desktop panel.
