Useful tip, on linux (not sure about other *nixes) you can view the ascii table by opening its manpage:
man ascii
It's been useful to me more than once every year, mostly to know about shell escape codes and when doing weird character ranges in regex and C.
It can be a bit confusing, but the gist is that you have 2 chars being show in each line, I would prefer a view where you see the same char with shift and/or ctrl flags, but you can only ask so much
