Why is this working for everyone else and not me?

This is my Default(Windows).sublime-keymap file: (same as the code above, but wrapped in ] and using “tab” instead of “enter”)

[code]

{ “keys”: “tab”], “command”: “move”, “args”: {“by”: “characters”, “forward”: true}, “context”:

{ "key": "following_text", "operator": "regex_contains", "operand": "^)\"\\]]", "match_all": true }, { "key": "auto_complete_visible", "operator": "equal", "operand": false } ] }

][/code]

I restarted it , tried many times, tried using different key combos, none seemed to work. What am I doing wrong?
