HyWikiWords
A HyWikiWord, or just wikiword, is a PascalCase word that starts with a capital letter and contains upper and lowercase letters only and has an associated referent (a link or an action). The default, most common referent type, is a HyWiki Page, an Org file with the wikiword’s name and a .org suffix that lives in hywiki-directory.
HyWikiWords are automatically highlighted and turned into hyperlinks to their referents as soon as you type them, without the need for any delimiters. By default, this happens only in HyWiki pages so as not to confuse new users. But with one setting, you can enable them in all text buffers and within the comments of programming language buffers. See HyWiki Mode.
