As one who codes in Vim, there is a huge time savings from living in a tool that closely maps your mind. Every cognitive load you can extract from the process of getting your vision down onto paper builds a compound interest in keeping your flow and momentum going while you work. If you're searching for menu options, or browsing a file directory, or doing the hundreds of other things it takes to otherwise navigate a computer file system, you can easily lose track of what you're trying to write in the first place. Call it saving time, or call it building productive power, but either way, it adds up fast. Not to mention the aesthetic pleasure of making your tools a joy to use.
