Using word completion
From Apache OpenOffice Wiki
If Word Completion is enabled, Writer tries to guess which word you are typing and offers to complete the word for you. To accept the suggestion, press Enter. Otherwise continue typing.
You can customize word completion from the Tools > AutoCorrect > Word Completion page:
- Add (append) a space automatically after an accepted word.
- Show the suggested word as a tip (hovering over the word) rather than completing the text as you type.
- Change the maximum number of words remembered for word completion and the length of the smallest words to be remembered.
- Delete specific entries from the word completion list.
- Change the key that accepts a suggested entry—the options are Right arrow, End key, Return (Enter), and Space bar.
