Hmmm. Saving a document is just making a record of the changes. With that in mind, some ideas: -record/disc (as the round image is generally universal, even inside floppies) -page (as in a document, as in to record something) -a red circle (talk about universal, just grey it out when no changes are detected) Or create a new symbol, say, two arrows overlapping, one pointing down, the other right. (Here and forward. And yes, I know not everyone uses those directions to mean those things, but I like the red circle more anyway.)
