what are "scope templates" in netbeans? I'm following a tutorial about jave EE/servlets where upon typing the key word "session" and hitting the TAB button a view counter appears on the servlets page. how can I configure the TAB button to achieve this task? also, where can I read more about this "scope templates" since I did not find any. thanks!

here is the tutorial (starts at 7:00) https://www.youtube.com/watch?v=UBNaiVWwAZw
