In which situations would you use a named clipboard as opposed to a sophisticated 'text' expander like Typinator?

@NaOH

I never thought of storing text expansions in variables until it was mentioned upthread. That's an approach I'll look into someday.

Never mind me doing that research after reading this post in another thread

Are variables' contents synced across multiple devices like macros?

No. KM Variables, Clipboard History, and Named Clipboards are stored only on the Mac that KM is running on, and are NOT synced. One alternative is to store the data you want sync'd in files in a system like DropBox. Then, in KM use the Read a File action and Write a File action to use in your Macros. You could also use a naming convention like "SYNC__MyVarName" to read all "sync" variables and write all, either periodically, or on demand.

which informs me that Variables don't sync. I work with multiple Macs so I'll just stick to a system I know achieves what I want and syncs.
