multiple "commands" in a single Sublime Text 2 user keymap shortcut

Is there a way to have multiple "commands" associated with one shortcut?

I have these two shortcuts. First shortcut makes the window on the left larger than the right one (in a 2 column view) and the next shortcut puts the focus on the first window. I tend to forget one or the other shortcut when coding quickly.

{
    "keys": ["super+alt+left"],
    "command": "set_layout",
    "args":
    {
        "cols": [0.0, 0.66, 1.0],
        "rows": [0.0, 1.0],
        "cells": [[0, 0, 1, 1], [1, 0, 2, 1]]
    }
},
{ "keys": ["ctrl+alt+left"], "command": "focus_group", "args": { "group": 0 } }

This question makes me sound like i'm lazy but i'd like to think of it as being efficient.

Any advice or suggestions, please?
