Lists old versions of a corrected message.

Installation
|
|
------------
|
|
::
|
|
|
|
/load display_corrections
|
|
|
|
Usage
|
|
-----
|
|
|
|
.. glossary::
|
|
|
|
/display_corrections
|
|
**Usage:** ``/display_corrections [number]``
|
|
|
|
This command lists the old versions of a message.
|
|
|
|
Without argument, it will list the last corrected message if there
|
|
is any. If you give an integer as an argument, ``/display_corrections``
|
|
will go back gradually in the buffer to find the message matching
|
|
that number (starting from 1, for the last corrected message).
|
|
|
|
If you are scrolling in the buffer, Poezio will list the corrected messages
|
|
starting from the first you can see. (although there are some problems with
|
|
multiline messages).
