Whenever I am writing (especially a long text), often I will accidently touch the touchpad with one of my thumbs. Then the following text will be typed in another location on the page (where the arrow cursor happens to be). Then I have to start over again or cut that text and paste it in the proper place.
I would like to keep using the touchpad, but do not want the touchpad to be able to select the position of the cursor. I would like to continue using the left button for that instead of Tapping the touchpad. How can I disable this tapping mode of the touchpad?
