Netscape is case-sensitive, which means that it differentiates between Document and document. In Netscape, the former could in theory be used as a variable, but the latter could not. Internet Explorer is not case-sensitive, which means that it does not understand any difference between Document and document. This is why both capitalized and lowercase versions of some variables are listed below.
