If you're interested in how that works, [^:] matches any character except a colon so the while thing matches lines where every character is not-a-colon. – Darael – 2017-07-11T11:28:55.047

  1. Control+F, go to "MARK" tab
  2. Find what : :
  3. check the box against "bookmark line"
  4. click "Mark all"

All lines containing : will be highlighted.

  1. Now, go to "Search" menu >> bookmark >> remove unmarked line.

Voila!
