从win转到ubuntu下开发
方向键太远了，所在在win下设置了sublime的快捷键：
{ "keys": ["alt+j"], "command": "move", "args": {"by": "characters", "forward": false} },
{ "keys": ["alt+l"], "command": "move", "args": {"by": "characters", "forward": true} },
{ "keys": ["alt+i"], "command": "move", "args": {"by": "lines", "forward": false} },
{ "keys": ["alt+k"], "command": "move", "args": {"by": "lines", "forward": true} },
用来替代方向键的左右上下，但是在ubuntu下alt+h和窗口的帮助菜单有冲突，按下alt+h总是弹出帮助菜单，有什么办法可以屏蔽掉窗口菜单弹出吗？
