Press Alt-F2 to display a small command-line window. Enter a Unix shell command (the SHELL environment variable is used to determine which shell executes the command), or one of the following:
Enter a URL to open a kfm window with the specified URL. You can omit the http:// or ftp:// if the server's name starts with www. or ftp., respectively.
Enter man:command to open a kfm window displaying the Unix man page for command.
You can use the up-arrow key to recall previously entered commands. Also, you can use the tab key to complete partially entered filenames, as in many shells.
