header_to_task hotkey (convert header to task, convert task to header)

[michaelmagistro]

The Readme lists the "header_to_task" attribute, which "If true, a project title line will be converted to a task on the certain keystroke". There's no documentation on what this keystroke is or how to set it. Being able to convert a task to a project or a project to a task would be quite useful, which seems like this is the intended purpose of this attribute.
