I have a hard time believing that in five years from now, people will still consider pressing a key on the keyboard the standard way to emulate a right click. Nevertheless, I can see the point in moving away from user-land decisions in the kernel. I will not pursue this one further, although it is a rather neat piece of functionality. > Overall I don't think we should enhance mousedev for scenarios where > proper solution is to install Synaptics X driver.

I can see nothing wrong with that. Henrik
