The file manager has a couple of other features that serve as handy shortcuts for common operations.
To open a terminal window with the current directory the same as the file manager, select Tools, Open Terminal, or use the keyboard shortcut Ctrl+T. This is handy when you get to a directory and discover that you need to perform some complex action there. Instead of opening a terminal window and navigating there manually, just type Ctrl+T. Of course, you can always use the integrated terminal emulator by selecting Window, Show Terminal Emulator Window.
To open a folder in a new file manager window instead of the current file manager window, click it with the middle mouse button.
To open a new file manager window with the same current directory as the current window, click the Gear icon in the toolbar (located on the right of the toolbar).
Sometimes you need to perform a file manipulation for which you just don't have permissions. In this case, it is possible to start a terminal window, su to root, and execute the commands by hand. However, to make it more convenient to overcome this situation, and to enable you to continue operating using a graphical file manager, KDE provides a way to launch a file manager with superuser (root) privileges.
To do this, select System, File Manager (Super User Mode) from the Application Starter menu. A special terminal window starts up and prompts you for the root password for your machine. Enter it, and a file manager with root privileges starts. To remind you that you are operating with special privileges, the handle of the menu bar in the file manager window is shown in bright red.
You can use this file manager window to perform operations that require root privileges. When you drag files between file manager windows of both types (root and regular user) onscreen, the window that performs the copy, move, or link operation is the destination window (the window being dropped on). This means, for example, that you cannot drag a file to which you don't have permissions from a root file manager window to a nonroot file manager window. You can, however, perform this drag the other way around.
To view a window in full-screen mode, select Window, Full-Screen Mode (Ctrl+Shift+F). This will expand the current window to fill the entire screen, including the normal panel and menu areas. It will also get rid of the Konqueror menu bar and status bar, leaving just the toolbars. This will give you the most screen real estate for viewing. To exit full-screen mode, click the icon with four arrows pointing toward the center of a screen.
