- A WORD is always delimited by whitespace.
- A word is delimited by non-keyword characters, which are configurable. Whitespace characters aren’t keywords, and usually other characters (like
()[],-) aren’t, neither. Therefore, a word usually is smaller than a WORD; the word-navigation is more fine-grained.
Example
This "stuff" is not-so difficult!
wwww wwwww ww www ww wwwwwwwww " (key)words, delimiters are non-keywords: "-! and whitespace
WWWW WWWWWWW WW WWWWWW WWWWWWWWWW " WORDS, delimiters are whitespace only
