in the manual: page 215 / 19.4.1 copying cue's: To copy in a cuelist other than the chosen one, or to copy between cuelists, specify the cuelist with the Listkey. For example: • List1Cue1CopyList2Cue2Enter: copies the contents of Cue 1 of Cuelist 1 to Cue 2 of Cuelist 2.
The manual is indeed incorrect (well it is correct, but the move of a cue has never been implemented). We do have a bug logged to implement the move command and also notes to remove the text from the manual until it is implemented.
IN the mean time you can copy a cue to another list then delete it from the original to achieve the same result. Remember to always consider the state of the cue when copying/deleting.
