assign multiple commands to the same key binding in ST2 - sublimetext2

Question

I have "Super+Alt+left" to set the layout so that the left pane is wider (66%) of the screen:
I would also like the same key stroke to focus on the left tab so that I can start typing immediately without a click or Ctrl + 0.
Here's what I tried. I added a new plugin:
import sublime, sublime_plugin
class ExpandAndFocusLeftPane(sublime_plugin.TextCommand):
def run(self, edit):
self.view.run_command("focus_group", "args": {"group": 0})
self.view.run_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]]
})
And I bound "Super+Alt+Left" to this new command.
{
"keys": ["super+alt+left"],
"command": "expand_and_focus_left_pane",
"args":
{
"cols": [0.0, 0.66, 1.0],
"rows": [0.0, 1.0],
"cells": [[0, 0, 1, 1], [1, 0, 2, 1]]
}
},
But it still does not do what i want it to do. Any ideas ?

First, you have to check if the "focus_group" and "set_layout" commands work as expected.
Open the console (View->Show Console) and try this:
view.run_command("focus_group", "args": {"group": 0})
You'll get a:
File "<string>", line 1
view.run_command("focus_group", "args": {"group": 0})
^
SyntaxError: invalid syntax
If you change it to
view.run_command("focus_group", {"group": 0})
it won't work. That's because "focus_group" and "set_layout" are window commands, so this will work:
window.run_command("focus_group", {"group": 0})
window.run_command("set_layout", { "cols": [0.0, 0.66, 1.0], "rows": [0.0, 1.0], "cells": [[0, 0, 1, 1], [1, 0, 2, 1]] })
So your plugin should extend sublime_plugin.WindowCommand and use self.window:
class ExpandAndFocusLeftPaneCommand(sublime_plugin.WindowCommand):
def run(self):
self.window.run_command("focus_group", {"group": 0})
self.window.run_command("set_layout", {
"cols": [0.0, 0.66, 1.0],
"rows": [0.0, 1.0],
"cells": [[0, 0, 1, 1], [1, 0, 2, 1]]
})
And ExpandAndFocusLeftPane should be ExpandAndFocusLeftPaneCommand.
