I'm on XBox and have an even worse habit - I'm so used to the VATS button being on the right shoulder I keep tapping that and bashing or holding it down to VATS the area and instead throw a grenade. I also do that other thing you guys are talking about, bashing instead of tossing and vice-versa.

The interface for selecting and using weapons sounds like a total pain in the neck.
