I suggest Windows and MAC use same keybings file

[yanzi1225627]

On Mac, this is my keybings:

[
   { "keys": ["ctrl+shift+f2"], "command": "sublime_bookmark", "args" : { "type" : "add"  } },
   { "keys": ["ctrl+alt+f2"], "command": "sublime_bookmark", "args" : { "type" : "toggle_line"  } },
   { "keys": ["f2"], "command": "sublime_bookmark", "args" : { "type" : "goto_next" } },
   { "keys": ["shift+f2"], "command": "sublime_bookmark", "args" : { "type" : "goto_previous" } },
   { "keys": ["ctrl+f2"], "command": "sublime_bookmark", "args" : { "type" : "goto" } }

]

I use only ctrl instead of super, keep same with Windows. ctrl + shift + f2, add mark, and ctrl + alt + f2 to remove mark.
