I’m a long-time vi user transitioning to sublime text, but haven’t been able to make basic ex commands work with vintageous or vintage with vintage_ex. Are block copy and move commands using bookmarks supported?

I would like to do things like, : (to go to the command line) and “'a,'b co .” to copy some lines. I get the command line, but the bookmarked range of lines are not copied.

Is this a “training issue”? What am I doing wrong? (OSX and Windows.)
