MacBook – How to avoid accidental right-clicks now that the Macbook trackpad is so big

I spent some more time debugging this, and it seems there are multiple setting locations (on multiple hosts) for the same setting.

AFAICT, each user gets his own host. The login screen uses a separate host. It makes sense to enable some settings (like Trackpad tap to click) for both these hosts.

Furthermore, OS X seems to have separate settings for Magic Trackpads and built-in MacBook Trackpads. The commands in my question only enable the Magic Trackpad settings.

Now, I try to enable it everywhere:

# Map bottom right Trackpad corner to right-click
defaults write com.apple.driver.AppleBluetoothMultitouch.trackpad TrackpadCornerSecondaryClick -int 2
defaults write com.apple.driver.AppleBluetoothMultitouch.trackpad TrackpadRightClick -bool true
defaults -currentHost write NSGlobalDomain com.apple.trackpad.trackpadCornerClickBehavior -int 1
defaults -currentHost write NSGlobalDomain com.apple.trackpad.enableSecondaryClick -bool true

You can do this on the Macbook Pro trackpad by pressing down with two fingers hard enough to engage the mechanical "mouse" button built in to the trackpad. Drag your item(s) to the desired destination and then release the pressure off the button and... voila! Windows will display the right drag menu at that point.

Unfortunately this doesn't allow "locked drags" where you can continue dragging long distances by picking your fingers up off the trackpad surface and quickly repositioning them to continue the drag.
