Use the Clear command to remove a selection from a track without placing it on the Clipboard.
When displaying waveforms for audio tracks, or notes or clips for MIDI tracks, selections include underlying automation and controller data. If the track is displaying automation data, only the automation data is affected by the edits.
If a portion of a clip was cleared, new clips are auto-created from the material residing outside of the selection. When Shuffle Clips is enabled, any subsequent clips slide over to fill any empty space.
