Hyperbole User Manual
7.4 Idstamps
Idstamps (permanent ids) are associated with each cell and can be
used in hyperlinks that are maintained as cells are reordered in a file.
See section 7.7 Links. Idstamps may also be displayed in place of the outline
level relative ids. Use {C-c C-l id RET}.
An idstamp counter for each outline starts at 0 and is incremented by
one each time a cell is added to the outline. This idstamp stays with
the cell no matter where it is moved within the outline. If the cell is
deleted, its idstamp is not reused.
The 0 idstamp is always assigned to the root node of the entire outline.
This node is never visible within the outline, but is used so that the
outline may be treated as a single tree when needed. Idstamps always
begin with a 0, as in 012, to distinguish them from relative ids.
