I won't say that this is a complete list, but I think this is a list of the most popular backslash characters (also known as escape sequences) that can be used in Perl strings. 

You can use these "special" characters (such as the [Tab] character) simply by putting them inside of Perl strings, like this:

  print "Here is a tab\t and then a form feed\f and maybe a bell\a\n";
