Special Characters
Certain characters are used internally; normally you do not even see them. But they can appear in the output of a {dump} command and can sometimes be used to create very intricate macros. \| matches any number of spaces, tabs or newlines. It even matches zero, but only between words, as can occur with punctuation. For example, \| matches the spot between the last character of a word and a comma following it.
