I have ctrl-space set as a global keyboard shortcut (Show Help menu) in Mac OS X.
Sublime Text overrides this in the default keymap:
        { "keys": "ctrl+space"], "command": "auto_complete" },
	{ "keys": "ctrl+space"], "command": "replace_completion_with_auto_complete", "context":
		
			{ "key": "last_command", "operator": "equal", "operand": "insert_best_completion" },
			{ "key": "setting.tab_completion", "operator": "equal", "operand": true }
		]
	},
I can just comment these out, but if I upgrade, then this change gets lost. Is there something I put in the user User key bindings file to “undefine” these?
