Character | Description |
\| | Matches any number of spaces, tabs, or newlines. 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. |
\^ | Matches exactly one space, tab, or newline |
\& | Matches exactly zero spaces, tabs, or newlines, but only between words. If the template ends with a parameter, the \& character is added at the end. |
