In Sublime Text 2 to use `Cmd-Shift-F` to reindent javascript with jsFormat without affecting other format, put this in the Key Bindings :

gistfile1.json

{
"keys": ["super+shift+f"], "command": "js_format" 
},
{
"keys": ["super+shift+f"], "command": "reindent" 
,"context":
[{ "key": "selector", "operator": "not_equal", "operand": "source.js"},
{ "key": "selector", "operator": "not_equal", "operand": "source.json"}
]
}
