Help in this context means discussion, advice, him showing me what he had done, me suggesting quick solution, or talking to him what to type, similar to pair programming. If _I_ had to actually write more than few lines of code, we'd just switch to my computer.
We have a standard IDE set-up for our team and require more junior devs to use it -- a least when starting out. It makes pairing with them easier.
The junior developer who insists on not using an IDE working with Java is precisely the one who needs the most help.
