Taskpaper files may be dragged into Tinderbox. Tinderbox automatically recognises Taskpaper tags and copies them to $Tags. The @done() tag also sets $Checked and $NameStrike; if the @done tag has a completion date, it is copied to $StartDate and $EndDate.
From v7.2.2, recognises and maps @due (to $DueDate), @start (to $StartDate) and @done (to $EndDate)
