I want to change the two letters before "@" and the first letter after "@"

  • Menu "Search" > "Replace" (or Ctrl + H)

  • Set "Find what" to ..@.

  • Set "Replace with" to **@*

  • Enable "Regular expression"

  • Click "Replace All"

You can do this by using a regex search/replace.

At the bottom, select Regular Expression.

In the Search for entry, you type in: ..@. In the Replace with, you type in **@*

Then press the button Replace All

This works because Regex searches will only replace if its search criteria matches exactly. The match is explained as follows:

..@. There are 3 dots and an @:

  • @ has no special meaning in regex so it means a literal @.
  • . means any character, exactly once. By writing .. it means 2 characters of any kind, as long as there are 2 characters.
