No Alignment and No Preference

[sang4lv]

After installing the package and restarting Sublime, I still can't see Alignment in the Preference Setting. And since Cmd+Ctrl+A pulls up the default screen capture keys, I modified 'Default (OSX).sublime-keymap' file to be
[ { "keys": ["super+shift+a"], "command": "alignment" } ]

However, I still can't see any selected lines aligned at all. I want the lines to be aligned by PHP array pointer '=>', which seems to be included in the package as well.

PS: tried to restart again, not working. And removed "alignment" from list of ignored packages, still not working. Just wondering, the key binding says 'super', but my user key bind doesn't have an entry from command to super. Could this be the issue?
