I have been in plenty of pairing sessions with people using IntelliJ where the speed of thought was not the limiting factor, but the speed of navigating around the project was. There's a few critical shortcuts (particularly pressing shift twice) which in my experience speed up the process of moving around a codebase to make changes or just study what is going on. Of course, everyone (myself included) develops certain habits and gets comfortable with them, and there is a mental cost with replacing those habits with more efficient ones. I don't have any time for people who are overly smug about their knowledge of different keyboard shortcuts, but I think it's equally unhelpful to discount the value of keyboard shortcuts.
