Speed up your work by utilizing various copy paste modes
Since songs usually contain repeating parts, Karedi lets you copy-paste parts of songs in various modes in order to help you avoid doing the same work twice.
Usually you want to use the standard copy-paste mode, it is especially useful for choruses where both tones & lyrics are repeated.
For copying verses (in which tones are very similar, but lyrics vary) or similar lines within verses using one of the merge modes may be more fitting.
