修改sublime列編輯快捷鍵

這個問題在好幾個電腦上搞了好幾次，每次都要搜搜，記錄備忘。

Ubuntu的sublime列編輯修改為簡單的快捷鍵：

路徑：Preferences→Key Bindings

默認是

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

可以在右側的User自定義部分覆蓋默認配置，修改為alt+上/下，也就是：

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