Backslash

And now it is time for your ASCII lesson of the day.

This, /, is a slash. You may recognize this character from our friend http://, pronounced aych tee tee pee colon slash slash. When in doubt, its a slash.

This, \, is a backslash. You'll know it from nothing other than archaic microsoft command-line stuff. You'll never use it unless you are a programmer or love the impotent Windows command-line interface.
