Ctrl + H
\d+:\d+\r\n
Then leave the “replace with” a just a blank space
See their manual online. Searching, Extended Search Mode:
\r is carriage return
\n is the line feed control character LF
\d is the decimal representation of a byte
This is handy to copy a transcript of a YouTube video and have just the words that were spoken, WITHOUT the time stamps they provide. Notepad++ is a free text editor, used mainly for coders, but anyone can use it and it is very powerful. Enjoy!
