I used to use this all the time.

I would highlight some code.... right click it... select "Surround
With"... select "Region" and type in the region name.

Now this option is gone.

I read another post that said you could get the same effect by doing
CTRL+K, CTRL+S.
When I pressed these keys it says that key combination "is bound to
command (&Surround With..) which is not currently available.

Any ideas what happened?
