Hi, since some users complained about the absence of ptr accel from local docs, I made an attempt to update it a bit. It's not much, but I figured that's better than nothing.
I'm open to suggestions though, in particular, I'd like to know where people look first when they seek this kind of information. In general, is it reasonable to point to the wiki from a man page? That one's separate if the answer is no. Cheers, Simon
