"Grammar checking
OpenOffice.org 3.1 incrementally improves the grammar checking
infrastructure. Version 3.0 allowed the LanguageTool extension to
provide as-you-type-your-mistakes-are-underlined-in-blue grammar
checking, and version 3.1 extends the spell checking dialog for
grammar checking.
"Overlining
You can be "overwhelmed," so can you be "underwhelmed" too? Yes,
and likewise to underlining, now you overline characters too.
Stranger yet, it turns out overlining has practical uses including
repeating decimals, line segments, high energy physics, logic, and

"Hyperlinks management
When you type a web site address, OpenOffice.org automatically
converts it to a clickable hyperlink. Many people don't know how to
convert it back to regular text. (The methods include Undo, CTRL+Z;
Default Formatting, CTRL+M; and disabling URL recognition in
AutoCorrect.) Now there is a more obvious method: the context menu
(also know as a right-click menu) features the new commands Open
Hyperlink, Edit Hyperlink, Copy Hyperlink Location, and Remove
Hyperlink."
