I want to delete all special characters (except dot) after the last word on the line, and to replace with dot.

This does the job:

• Ctrl+H
• Find what: [^a-z]*$
• Replace with: .
• UNCHECK Match case
• CHECK Wrap around
• CHECK Regular expression
• Replace all

Explanation:

[^a-z]* # 0 or more non alpha
$ # end of line
