Auto-Completion

What is Auto-completion Notepad++ offers automatic completion of various sorts of text after you have entered an initial substring (or prefix), which can save you having to type all of a long word (and potentially save you mistyping it). For instance, if you’re coding in JavaScript and type syn, Notepad++ can present synchronized (a JavaScript keyword) as a suggestion. You accept the suggestion by typing the completion key (see “Automatic completion", below), and the word is completed within your buffer as if you’d typed it all out.
