In Gmail, sending good replies with just the right amount of quoted content from the original message can mean highlighting clumsily around the text you want to keep; or selecting just what you want to quote and pressing a key.
Reply Quoting Only Highlighted Text in Gmail
To quote only what you have highlighted in the original message when replying in Gmail (instead of the entire email):

- Make sure Enabled is selected for Quote selected text.
- Click Save Changes.
- highlight the portion you want to quote in your reply when viewing an email.
- Press r.
