How to sync fish's universal variables across different computers?

If you change some universal variables, how do you sync them across computers? The comments on the fishd.* files make it seem like a bad idea to sync those files. And fishd's man pages don't seem to indicate it's user serviceable.

In all gui text editing, ctrl-arrow moves the cursor by word, and holding shift selects as the cursor moves. Thus ctrl-shift-left selects the previous word. Fish already has the former but I want to implement the latter. I tried doing something like…
