Here, from the wikipedia article on typographic dashes, is a pretty priceless demonstration of just how much more pleasant a Mac is to use when compared with a Windows PC:
Rendering dashes on computers
- In Mac OS X […] an en dash can be obtained by typing ⌥+-, while an em dash can be typed with ⌥+⇧+-.
- In Microsoft Windows running on a computer whose keyboard has a numeric keypad, an en or em dash may be typed into most text areas by using their respective Alt code by holding down the Alt key and pressing either 0150 or 0151. The numbers must be typed on the numeric keypad with Num Lock enabled. In addition, the Character Map utility included with MS Windows can be used to copy and paste en and em dash characters into most applications—along with accented letters and other non-English language characters.
