Why "tab_completion": false, ?

@ttscoff suggested to add context to key shortcuts: https://gist.github.com/2951063#comment-354177

So you could use super+shift+l in javascript/php and it pastes the appropiate syntax.

"open_files_in_new_window": false is also handy.

For easier comments I use these two:

{ "keys": ["ctrl+q"], "command": "toggle_comment", "args": { "block": false } }, { "keys": ["ctrl+shift+c"], "command": "insert_snippet", "args": {"name": "Packages/User/InsertSectionComment.sublime-snippet"} },
