| <h1 class="Head">Find/Replace with Regular Expressions</h1> |
| |
| <p> |
| The <strong>Find</strong> field allows regular expressions as defined by the <a href="http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html">Pattern class</a>. |
| <br>Additionally, it supports \R, which matches any form of line delimiter (Unix, Windows, Mac OS 9). |
| Note that \R does not work inside []. |
| </p> |
| |
| <p> |
| The <strong>Replace</strong> field allows the following constructs: |
