  • Ctrl+H
  • Find what: ^w+h+w+h+w+K.*$
  • Replace with: LEAVE EMPTY
  • CHECK Wrap around
  • CHECK Regular expression
  • Replace all

Explanation:

^           # beginning of line
    w+         # 1 or more word character
    h+         # 1 or more horizontal space
    w+         # 1 or more word character
    h+         # 1 or more horizontal space
    w+         # 1 or more word character
    K          # forget all we have seen until this position
    .*          # 1 or more any character but newline
$
