synaptiks is a touchpad configuration and management tool for KDE. It provides
a System Settings module to configure both basic and more advanced settings of
the touchpad. Additionally it comes with a little system tray application,
which “manages” the touchpad. It does not only provide a global hotkey to
conveniently switch the touchpad on or off, it can also do this automatically
while you are typing, or if you plug in an external mouse.
