This module implements inline tasks in Org-mode. Inline tasks are
|
||
|
|
tasks that have all the properties of normal outline nodes, including
|
||
|
|
the ability to store meta data like scheduling dates, TODO state, tags
|
||
|
|
and properties. However, these nodes are treated specially by the
|
||
|
|
visibility cycling commands and by the export commands.
|
||
|
|
|
||
|
|
Visibility cycling exempts these nodes from cycling, so whenever their
|
||
|
|
parent is opened, so are these tasks.
|
||
|
|
|
||
|
|
Export commands do not treat the tasks as part of the sectioning
|
||
|
|
structure, but as a spe
