Did you know that you can use a to append to the end of a selection? This comes in handy with a comma separated list because you can split to select each item and quote them simultaneously. Or use different text for begin and end like braces.
Yep! This is pretty nifty for the reasons you mentioned. What I’m really curious is for a behavior almost like what <a-S> does. I’ll update my main post to explain why <a-S> doesn’t work.
