An External CueLink is created at the location where the Cue was dropped. The CueLink contains the name and ID of the original Cue.
When you drag and drop a Cue onto the timeline to create an External CueLink, the parent CueSheet is set in the reference CueSheet by default.
To create an External CueLink from drag & drop without identifying a CueSheet, drag and drop a Cue while holding down the Alt key.
