Changing double finger tap action and more in Windows 8

Changing double finger tap action and more in Windows 8:
If you have a multitouch supported touchpad in your laptop and windows 8, you can do much customization.
Just make sure that your Synaptics driver version is 16.3.x.
In registry editor:

Open resitry editor (Run>regedit)

Goto HKEY_CURRENT_USER>Software>Synaptics>SynTP>TouchPadPS2
There will be many keys like 2FingerTapAction, 3FingerTapAction,..
If you want to use 2 finger tap as right click,
then edit 2FingerTapAction and give it the value 2
Values   Actions
   1       Left Click
   2       Right Click
   3       Middle Click
   0       No Action(Disable)
   4       Lock cursor position.
you can change any value to any.Just restart to make them effective.
Using Synaptics settings:
Goto mouse properties from control panel or Run>main.cpl

Choose Device Settings Tab and then Settings.

In Synaptics settings, you can choose whatever you want.

Most options have settings icon by which, you can see elaborated settings.

There will be an animation for every option, so it won't be hard to learn.

My personal setting is Disabling reverse scrolling direction.
