What does Save Offline do

[MrSkeletonpants]

So yesterday i was working all day on a song. It was getting late so I thought "Hey, I'm gonna save it so I can work on it tomorrow." My internet was supposedly ***** and it said to save it offline. I'm fairly new to Online sequencer and I don't know what Save offline does. I saved the sequence to a document file. What do I do then? :s

You copy the text using ctrl+c and paste it in a new sequence using ctrl+v (NOT the button)
