Copying pasting and deleting lyrics

Let's say I'm entering lyrics. Most of them are correct, but part way through the song, I entered an incorrect sequence of lyrics. Is there a way to select and delete those lyrics all at once, instead of one-at-a-time, without affecting lyrics that come before or after?

Let's say a sequence of lyrics repeats in a song. If I don't want to enter them all over again, is there a way to copy them and paste them in a different part of the song?

Thanks!

By the way, on the whole, lyric entry is a miracle. It's easy, fast, intuitive, does almost everything I need. Really appreciate it.
