When searching for a regular expression, you can click the Free button on the Search toolbar to turn on the “free-spacing” search option. A free-spacing regular expression ignores whitespace and line breaks. It treats # as starting a comment.
Turning on this option is the same as putting the mode modifier at the start of your regular expression. If you do use the mode modifier or then the mode modifier overrides EditPad’s search option.
