Code Hints suggest you best guess from editor. Suggestion takes into account existing User Templates, Auto Correction data, keywords from dictionary and statistical data collected by editor engine during your typing.
The best guess calculation is programming language and context dependent.
You can agree on suggestion by Tab or Enter and editor would complete rest of word for you.
If you type code template key, HippoEDIT will show you Code Template description and will Code Template text if you accept hint.
