Useful improvement of x230 touchpad functionality

[TOTAL]

The trackpad's left button has stopped clicking so until I replace the keyboard, I have switched to using the touchpad. Never worked 100% reliably, with right button responding only to every second click and the left button becomes virtually sticky at times, but the greatest nuisance has always been the proneness to accidental touching while typing. There were some driver versions which tried to address that but never reliably.

So I have some up with an idea - and gemini put it to action - that the touchpad and its left click should only work when fn button is pressed. Makes you use the mouse as a minigun, so no drinking coffee while navigating the screen but it has become completely immune to accidental touches.

Here is how to do it.

1. Install autohotkey
2. create a file touchfreeze.ahk
3. modify its content with below code.
4. save the file and double-click it.

enjoy.
