What are the possible arguments to delete_word command?

[rrdrake]

I’m looking to customize the control+backspace key. I see this in the sublime-keymap:

{ "keys": "ctrl+backspace"], "command": "delete_word", "args": { "forward": false, "sub_words": true } }

Does anybody know what the possible (useful) arguments to the “delete_word” command?

Thanks,

According to its definition in packages/Default.sublime_package, those are the only two.
