The directory tree window appears when you type kcd without any other parameter. Following are the meaning of different colors and symbols used to display a directory in the tree. Green (color console) or underlined (B&W console) Accessible normal directories. You can move the highlight bar and press Enter to exit kcd and jump to this directory. Yellow (color console) or underlined bold (B&W console) Accessible symbolic link. If the link points inside the directory tree, selecting this directory will move to the linked directory while remaining in the directory tree window. On the other hand, if it points outside, selecting it will exit kcd and jump to the target directory. Gray (color console) or normal (B&W console) Inaccessible directory. You don't have permission to change into this directory. [skipped] Directory skipped from scanning so that its subdirectories are not displayed. /dev is always skipped since its content is really entry points for kernel drivers and this takes very long time to scan. /proc is also skipped due to continuously changing content. You can configure other directories to skip using SkipDir setting. See `Configuration File' section below for more information. [*] Directory is not currently present in the saved file. They are added automatically to the screen when current directory is not in the file. As of the current version of kcd, added directory are not written to file. To update your directory to disk, you have to rescan directory. [unreadable] You don't have either read permission to display the content or execute permission to change to this directory. [outside tree] This is a symbolic link that points outside saved directory tree.
