Reply To: GREP query to find first space of a given paragraph style

Great question… sorry, I should have done that. Was typing too quickly. :-)

• The stuff in the parentheses is the stuff you want to keep.
• \d means “any digit”
• the stuff in the brackets means “any one of these things”
• the +? means “one or more of these”
• means “any space”

So the result is “find a digit, followed by one or more digts-or-dots, followed by any space… then replace it with the numbers and dots, followed by an em dash and an indent-to-here character.”
