Very nice, I'm copying that one! You don't actually have to use macros for that. This will suffice (in your .sublime-keymap):

    {"keys": ["alt+up"], "command": "move", "args": {"by": "stops", "empty_line": true, "forward": false}},
    {"keys": ["alt+down"], "command": "move", "args": {"by": "stops", "empty_line": true, "forward": true}},
    {"keys": ["shift+alt+up"], "command": "move", "args": {"by": "stops", "empty_line": true, "forward": false, "extend": true}},
    {"keys": ["shift+alt+down"], "command": "move", "args": {"by": "stops", "empty_line": true, "forward": true, "extend": true}},

(Changed it to alt instead of ctrl because that's how I like it.)
