Notepad++ want to use RegEx to seek minimum-length strings

Question

Only been using Notepad++ v 5.92 for a few weeks, and RegEx for a few hours (!!) I want to use Find & Replace for UPPERCASE strings of a minimum length to change them to "Title Case" or "Sentence case".

I found patterns in an online tutorial for the string

([A-Z])

Pattern for length of string \{5,50\} How do I combine this syntax in Notepad++ to get a working find instead of "not found" message?

Answer 1

Notepad++ doesn't support {x,y} operator. Even if it did - you cannot use it to replace the uppercase with lowercase/titlecase strings.
