For example, the command Copy QUEUE=MyQueue will copy selected files using the queue MyQueue. You could then configure a button or hotkey to copy using your named queue when a particular key was held down (e.g. Shift) - that way you could force the queue to be used when desired, even if Opus would ordinarily not queue the operation.
So if I have started some operation by Copy QUEUE=MyQueue
then I want to add to the queue
Select ALL
then
GetSizes HASH=md5
how I need to do to achieve such result?
