如果有使用karabiner的话，可以把一条命令映射到一个按键上，比如cmd+F9
只需在private.xml里增加配置
<vkopenurldef>
<name>KeyCode::VK_OPEN_URL_SHELL_goagent </name>
<url type="shell">
<![CDATA[ python ~/Documents/goagent/local/proxy.py ]]>
</url>
</vkopenurldef>

<item>
<name>Change Cmd + F9 to execute goagent</name>
<identifier>private.cmd_f9</identifier>
<autogen>
__KeyToKey__
KeyCode::F9, ModifierFlag::COMMAND_L,
KeyCode::VK_OPEN_URL_SHELL_goagent,
</autogen>
</item>
