That would be "snippet expansion" (pioneered in TextMate, if I'm not mistaken — well, that's where I saw it first).
"Autocompletion" is… "automatic": you type the beginning of a method name and you get a contextual menu following your cursor showing a list of suggestions. Many editors have that feature, either built-in or via plugins, but it's definitely an area where IDEs shine. If the editor/IDE has a way to infer scope, you get good completion, if not, you get mediocre completion.
But "snippet expansion" or "templates" as they are called in some IDEs is very easy and doesn't require statical analysis or whatever.
