Splitting a selection
s keeps the matches. Its capital sibling S does the opposite: it keeps
everything between the matches. Think of it as splitting the selection
wherever the pattern occurs.
That’s exactly what you want when a line is a list. Select the line, press
S, type the separator, and you get one cursor per item, with the separators
left out of the selections. From there c rewrites every item, ~ changes
its case, and d deletes it.
The prompt works the same way as s: the pieces light up as you type, and
Enter keeps them.
