I just installed Ubuntu on my Acer Aspire 5610Z.
I'm looking for a way to program the touchpad and the extra 4-way scroll button (between the left click and right click buttons).
By default it scrolls up, down, left & right. Since I can set the right edge of the touchpad to scroll up & down, I'd like to reconfigure these buttons.
I would like to set it up so that Up would middle click, Left would go back, Right would go forward, and down would switch tabs or apps.

If that isn't possible, are there any mods for adding middle-click somehow (other than ctrl-click)

Also, if anyone knows of a way to configure the other media and app buttons that come on this laptop, please share.
