Thank you.  

After looking into this a bit, I'm not seeing a handy way to set
something else permanently. 

In fact it appears there are nearly half a dozen ways to invoke
expansion.

space, <RET>, C-x ' (At least two more key combos that I already
forgot)

So there must be a list or regex or something.

I'd like to add some other char to the list somehow.

Any clues how I might do that?
