Keyboard Navigation Plugin for Konqueror is a plugin that lets you navigate the Web with keyboard shortcuts (also known as hints) as seen in Vimperator and Conkeror. After pressing the shortcut key, the plugin displays highlighted numbers (hints) at each link. You may decrease the number of highlighted links by entering substrings of its link text. You then enter the number of the link to visit or hit enter to visit the link numbered 0. If there is only one highlighted link left, it gets visited automatically.
KNoFault is a tool that protects your files with XOR encryption. It can use a username and a password to encrypt, or it can any file as a key. When given an incorrect decryption key, instead of showing an error it will encrypt the already encrypted file with the new info. This makes it possible to encrypt a file several times so that only two people together can use it, for example.
