The designator current refers to the note which Tinderbox is currently exporting. Where a note is exported to its own page, current is the same as this.
However, if a note includes children or other notes, current differs from this in the included notes reflecting the note actually being processed (and not the note that initiated the export).
Note that, when it appears outside an export template (e.g. in an agent or container action), current is synonymous with this.
