Number of steps. Be aware that asking OOo to remember more
changes makes it consume more memory.
Tracking changes to a document
You can use several methods to keep track of changes made to a
document.
• Make your changes to a copy of the document (stored in a
different folder, under a different name, or both), then use Writer
to combine the two files and show the changes you made. Click
Edit > Compare Document. This technique is particularly
useful if you are the only person working on the document, as it
avoids the increase in file size and complexity caused by the other
methods.
• Save versions that are stored as part of the original file. However,
this method can cause problems with documents of nontrivial size
or complexity, especially if you save a lot of versions. Avoid this
method if you can.
• Use Writer’s change marks (often called “redlines” or “revision
marks”) to show where you have added or deleted material or
changed formatting. Later, you or another person can review and
accept or reject each change.
