If you use and love GoldMine email like I do, this is a nice little tip.
When replying to an email you may only want to quote part of the original text.
To do this, select the text you would like to quote with your mouse (highlight it).
Then hit Reply. You'll see that only the selected text is now quoted at the bottom of your reply.
If your GoldMine email doesn't quote by default, go to
Tools | Options | Email | More Options
Make sure thet "Quote original message by default" is selected.
