Sub-Indexes
You can also continue writing in a specific Thread's section by repeating a previous index, or identify it as a sub-index, like this:
#threadit 2:1
This section is identified now by index "2" and sub-index "1". It will be displayed in the web page after the content of index "2" or "2:0".
Sub-indexes identifies a sub-section that will be displayed in the web page after the previous sub-index (in this case it will display after the index "2").
It can also be further used with commands, such as "overwrite" and "append". We will see some commands in action in the following sections.
Conditions
Follows the same conditions previously listed for "Index".
There can be only one level of sub-index ("2:1:1" is not valid).
If the parent index wasn't identified in any other toots of this thread (in this case the index "2" or "2:0"), then it will be displayed in the web page after the parent toot's (the one you replied to) most recent reply containing the hashtag "threadit".
