[TYPO3-english] Keyword autolinking

[maaboo]

Hi!

Is there an extension (or, if no - how much it will cost) which can set
links to list of keywords automatically?

For example, we write an science (or popular) article and think that some
people may not know all terms. So we create a list (for whole site, or for
it's part) and system can link these words to their pages with explanation
automatically if word is found at first time.  (If i understand Wikipedia
use this mechanism).
