I'm always surprised at how many of my non-techie friends struggle with keyboard shortcuts; it seems to be deeply counterintuitive to me, some of the contortions that people go through because, cognitively, they wont or can't devote space to the shortcuts. I have a sneaking suspicion that the sort of fearful respect with which they treat computers is the norm. Anything that makes using a computer simpler is IMHO a good thing; if it increases the utility f computers for the 99% at the cost of messing with the expectations of the 1%, well that seems like a reasonable trade off to make.
