Is there a simple way to copy all regex matches in a file, and paste it into a new buffer? If not, maybe highlight all matches and delete anything that is not a match?

You can use :g/regex/d to delete lines that match a regex, like so:

code:

> echo old.txt:; \
  cat old.txt; \
  vim old.txt +:g/^delete/d +:w\!\ new.txt +:qa\!; \
  echo new.txt:; \
  cat new.txt 
old.txt:
delete a
keep a
delete b
keep b
new.txt:
keep a
keep b

It's probably better to just use grep though:

code:

> echo old.txt:; \
  cat old.txt; \
  echo grep:; \
  grep '^keep' old.txt 
old.txt:
delete a
keep a
delete b
keep b
grep:
keep a
keep b
