I will modify the document since it mentions a MaxTabTime and MaxTabMove when it should be MaxTapTime and MaxTapMove as mentioned in the man pages of synaptics.
The package "ksynaptics" is not in the package database for the default repositories or the community. gsynaptics is in community, which I will note in the article, but I'm not sure what to do about the kde tool.
Well, add ksynaptics as well. Even though it is not in the repos, someone may still want to obtain and compile it. It is available from AUR, and most archers, I presume, use or know how to use AUR. --Foxbunny
