Try a regular expression replace of
(A candy is true)|(A candy is false)
with
(?1A candy is false)(?2A candy is true)

Thanks! This works :) . I went to this page before but i must’ve misunderstood

"For example, the format string “(?1foo:bar)” will replace each match found with “foo” if the sub-expression $1 was matched, and with “bar” otherwise. "

I tried to use it with “:” between alternatives, but that didn’t quite work. Your solution with (?N smg ) works just right.

find what : A candy is .*$

Search mode: Regular expression

This changes whole subject to a small regex workaround that doesnt work as indented. I Want to have both alternatives and i want to replace based on which alternative is found. So if you find “true” replace with false, if you find “false” replace with true. this is again simplified. Once i get this to work, the alternatives will be contucted of regexes and the replace will be also based on groups i find using regex. I only pinpointed the part i have trouble with - How to adress alternative in find - so that people don’t go into understanding unnecessary commands when question is simple.

Hope this clarifies the problem.

When using find, you can do something like (X|Y) and notepad will find both of these

find what : A candy is .*$
