I often use the ctrl+two-finger-swipe screen zoom feature in OS X. Now that I've upgraded to a device with a multitouch trackpad, it would be great if I could do this one-handed, instead of using my other hand to reach over to the control key. I'd like to set up a trackpad gesture to do it (e.g. a three-fingered pinch doesn't seem to do anything by default, so that would be good). However, it seems that the standard solution, bettertouchtool, doesn't have the capacity to use this OS feature.
I'm guessing this means that it isn't possible (for now) to do what I want, but just in case, does anyone know of a way to set up a trackpad gesture to control the screen zoom feature, either using bettertouchtool or some other way?
