not working mac os mavericks - sublime text build 3065

installed trhough package control.

package control settings > default (cannot be edited)
[
{
"keys": ["_super_+shift+r"], "command": "browser_refresh", "args": {
"auto_save": true,
"delay": 0.0,
"activate": true,
"browsers" : ["chrome"]
}
}
]

package control settings > user (can be edited)
[
{
"keys": ["_command_+shift+r"], "command": "browser_refresh", "args": {
"auto_save": true,
"delay": 0.5,
"activate_browser": true,
// "browser_name" : "all"
"browser_name" : ["chrome"]

command + shift + r
does not produce any result, no saving either.
