SublimeText Multiple Cursors or Carets

I’ve been using MacVim forever, and finally switched to using SublimeText with the vintage mode enabled. It’s scratching many of the itches I’ve had, but one of the main things I liked to do in vim was stuff like prepending content to multiple lines by selecting multiple lines and then typing:

:norm!Iprefix content

After a little digging, I found that you can add the following keybindings:

    { "keys": ["super+up"], "command": "select_lines", "args": {"forward": false} },
    { "keys": ["super+down"], "command": "select_lines", "args": {"forward": true} }

Now you can hit your command key and an up/down arrow to get multiple cursors, and then perform the insert to all the lines.
