Is there a reg hack (or anything, except post-it notes) to disable the touchpad where the mouse buttons are? The pointer is moving around whenever I try to click on a mouse button. (Shouldn't too be specific to my Lenovo Yoga 2 or Windows 8.1).

Looking in the mouse settings I found I have Synaptics ClickPad V8.1 on PS/2 Port.

I've been googling and tinkering for hours and days with the registry but no luck with finding the correct keys or values that makes any change to the touchpad button areas...

In regedit, I found it most likely to be related to some values in Synaptics registry keys at HKEY_CURRENT_USER\Software\Synaptics\SynTP\TouchPadPS2\ZoneManager\EdgeRegion\0 where I found ZoneSpec set to some strange values 00 04 00 00 50 12 00 00 30 11 00 00 50 0e 00 00 but no changes I've tried so far has had any effect.

The only change I've actually been able to make to the touchpad at all is at HKEY_CURRENT_USER\Software\Synaptics\SynTP\TouchPadPS2, changing 1FingerPressButtonAction value from 1 to 0, disabling the normal click function.

PS: In linux this seems much easier, see for example https://askubuntu.com/questions/221664/how-to-tune-touchpad-for-smaller-area where the bottom edge of the touchpad area is changed by synclient AreaBottomEdge=**VALUE**

It is entirely up to the touchpad and driver how to interpret the touch positions, and it sounds like you have exhausted the search within your driver, for a setting that will improve the behavior. Interestingly, exactly where the "button zones" are, is up to the device/driver--touch and click are separate functions. Most likely, the entire touchpad, less the right button zone, can be used to create a left (ie primary) click. Or even no touch (eg press with a piece of plastic).

Unfortunately, touchpad makers decided "clickpads" were desirable without consulting folks like you and me. Give me mechanical buttons, please!

If you are lucky, there is a later driver at Synaptics website that will behave better. At the very least, when you actually click the button, it will hold the cursor still, if it is well designed and implemented.

In the meantime, try using your finger tip so you get less change of shape as you increase pressure to click.

If you change your mind about the "post it note" solution, probably one won't do it. You'll either need a fairly thick stack, or try some metal foil. ;)
