Example:

1. Not working.
   Find:

   Code: Select all

   $0

   Replace with:

   Code: Select all

   [$&]

   \& will still be matched in new syntax, only for text without line breaks.
2. Old syntax.
   Find:

   Code: Select all

   \&

   Replace with:

   Code: Select all

   [&]

P.S. No folding functions in TextPad?

Isn't the whole sense of $0 to be used in a potential replacement instead of a finding? Just like $1, $2, $3 etc. are used for groupings in the match? Using $0 means the whole matching regex without any groupings, so using it to find anything becomes logically impossible, since it would refer to itself.

I did my best to format your post despite your settings to not parse any BBCode (mainly because then it's less ambiguous what your actual regex/replacement should be, secondly to have a true list) - is this the replacement you really wanted? An opening square bracket, then your whole match, then a closing square bracket?

Yes: such a feature does not exist. In contrast to f.e. Notepad++ TextPad can handle very big files and use search & replace on those in a timely manner, while Notepad++ takes a very long time. Folding lines surely comes with a performance impact somewhere, and I'm glad TextPad doesn't have it so far.

As AmigoJack writes, using $0 in a search expression makes no sense.
It matches the end of a line ($) followed by a "0". But that sequence exists nowhere, as the end of a line is followed by a newline character sequence (1 or 2 characters).

Keep in mind that regexes and replacements are entirely different things and have different syntaxes.

Thanks for your replies!
If you please could suggest a replacement expression for putting, say, brackets around (a few lines of) selected text. Or just a find string to match any selected text.
Sorry for unintended confusion. I looked for an alternative to \& in a wrong place:
Replacement Format Syntax Conversion
Old & (probably the POSIX syntax used prior to TextPad 7)
Perl/JavaScript $0

If you lookup Perl Modifiers in the section on Regular Expression Syntax in the help file, it explains how to match over multiple lines using "(?s)". Hence, to quote a multi-line string, select it then:

Find what: (?s).+
Replace with: "$0"
Replace All in Selected Text.
