For users on Linux and Unix, KDE offers a full suite of user workspace applications which allow interaction with these operating systems in a modern, graphical user interface. This includes Plasma Desktop, KDE's innovative and powerful desktop interface. Other workspace applications are included to aid with system configuration, running programs, or interacting with hardware devices. While the fully integrated KDE Workspaces are only available on Linux and Unix, some of these features are available on other platforms. In addition to the workspace, KDE produces a number of key applications such as the Konqueror Web browser, Dolphin file manager, and Kontact, the comprehensive personal information management suite. The list of applications includes many others, including those for education, multimedia, office productivity, networking, games, and much more. Most applications are available on all platforms supported by the KDE Development. KDE also brings to the forefront many innovations for application developers. An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner, eliminating the complexity and tediousness of creating highly functional applications.
KKBSwitch is a keyboard layout indicator for KDE 2 and 3. It is useful when you have configured the XKeyboard extension of your X Server to have more than one keyboard group, for example US/ASCII and Russian. It displays an icon in the system tray that indicates which layout is currently active. Note that it does not help you configure XKeyboard, it merely serves as the indicator of the current group. You still have to configure XKeyboard by editing the XF86Config file. You can switch keyboard groups by clicking the icon or selecting the desired group from the icon's menu. Icons corresponding to different groups are configurable (chosen from the country flag pixmaps that ship with KDE). There is also a "Toggle mode" (toggles between the two most recently used layouts). The keyboard layout can be switched for each window separately, per-application (as in Windows) or globally.
Krename is a very powerful batch file renamer for KDE which can rename a list of files based on a set of expressions. It can copy/move the files to another directory or simply rename the input files. Krename supports many conversion operations, including conversion of a filename to lowercase or to uppercase, conversion of the first letter of every word to uppercase, adding numbers to filenames, finding and replacing parts of the filename, and many more. It can also change access and modification dates, permissions, and file ownership.
