I was using that Google 3D plot viewer thing the other day and assumed right-click-dragging would do something for me. It didn't, and it occurred to me that the reason we have this is that Microsoft, Apple, or some other microcomputer vendor once decided people were too dumb to know they have more than one finger. And now on the subject of double-clicking, it occurs to me that if the one-finger thing hadn't been the way, everything that was ever a double-click action could've just been a single click on the next button over. Which would be simpler.
