I know. It was just an example to illustrate the sort of syntax that you'll find more of.
If I myself actually properly knew Vim, I would have given you an example that by itself is most definitely quicker than normal keybindings, too. But I figured, if you actually care to understand, you'll see that it's just an example, if you don't, then you won't.
All I know, is that you can find videos of people using Vim well and they're most definitely faster than anyone I've ever seen with a normal text editor.
