====== Changing the Perl scheme to have folding comments ======
Locate perl.scheme at Programmer's Notepad\schemes folder and edit it. Search for the line that starts the language declarations:

<code xml>
<language name="perl" title="Perl" folding="true">
</code>

and add the following two values just before the right bracket:

''foldcomments="true" foldcompact="true"''

Save perl.scheme. Now, when you edit a file declared as Perl, consecutive lines of comments (starting with #) can be folded to show just the first one.
