In OS X Google Chrome, swiping left or right with two fingers goes forward or back in the history. I've been trying to use synaptics and touchegg to do this but can't seem to figure it out. How can I emulate this behavior in Ubuntu? I have a Macbook Air.
I would suggest trying easystroke for this task. I have not used it myself (since my touchpad does not support multitouch :(...).
BTW, Chrome does not have the feature in Ubuntu because while Ubuntu does support multitouch through the use of a tech called utouch, most applications and toolkits do not yet support utouch, and are waiting on X to pick up multitouch support itself, which is probably the better solution.
