Enable clickpad middle click on Ubuntu 12.10

view story

http://askubuntu.com – Currently running ubuntu 12.10 on my Acer Aspire S3 ultrabook and i've been fighting with it trying to get the mouse middle click to use three finger tap on it. I could do this without an issue on 12.04 using this method - MacBook Pro Touchpad Optimization 12.04 LTS but this doesn't work on 12.10. Any help would be greatly appreciated. Thanks. (HowTos)
