Hello I have a touchscreen tablet in gnome there is an option (Trigger secondary click by holding down the primary button). My question is is there a KDE Debian wheezy similar function? for Tablet -Vpad10 intel atom n455 1Gb Thanks.

I'm not aware of any specific option in KDE itself - however we don't include device specific control panels for touchpads or touchscreens at the moment. Given that GNOME supports it, X likely does as well.

I would recommend searching for information concerning "xsetwacom".
