How do I change two letters closest to a string and one letter immediately after a string using Notepad++?
I have a list of emails, and I want to change the two letters before "@" and the first letter after "@" using Notepad++.
For example:
username@yourdomain.com
becomes
userna**@*ourdomain.com
notepad++

Just an obvious remark, the concrete example you gave shows how useless this pattern would be to anonymize email addresses. It’s usually better like x******@y***.com

@eckes would that even be possible in N++?

@WELZ Yes but its more work, a half working sample would(.)[^@]*@([^.]).*(.[a-z]+)
use 3 capture groups which you can address in the replace with string:1***@2***3
- uses a fixed number of mask characters but this is actually good.
