This is the vim search & replace patterns that I built-up. The difference between the first and the second example is the addition of the \%V which tells vim to restrain the search & replace operation you’re about to do to the visual selection. That was tricky!
# Proper-case capitalize everything on line
s/\<./\u&/g
# Proper-case capitalize everything under visual selection
s/\%V\<./\u&/g
# Replace hyphens in everything under visual selection
s/\%V\-/ /g
