The Hotwords feature allows you to make certain words in Wiki pages appear consistently as particular hypertext, i.e., specific external links.
With administratrive privileges click Admin, then click the Features icon. Check the appropriate checkbox for Hotwords and save your changes.
They are very useful for creating glossaries.
Note: Take care with your choice of HotWords, especially if they are acronyms. Combinations using a common noun and consonant for HotWords can cause great problems in your links.
