allows you to easily configure the extra function keys of your keyboard. This means that you can define, for every individual function key, what to do if it is pressed.
keytouch configures the actions asociated with each key.
keytouch-keyboard is a wrapper that acquires root permission to run keytouch-keyboard-bin (with su-to-root) and optionally (if --restart-keytouch is given as argument) calls keytouch. Use this to configure the keyboard definition file to use.
keytouch and keytouch-keyboard-bin accept the standard gtk-options.
keytouchd, keytouch-acpid and keytouch-init have no options and are intended to be started by the system Xsession and startup scripts. They provide the infraestructure and initialization required for the rest of the system.
