Editor Fluency:

"Tip 27: Achive Editor Fluency

We've talked before about tools being an extension of your hand. Well, this applies to editors more than to any other software tool. You need to be able to manipulate text as effortlessly as possible, because text is the basic raw material of programming. ...

We are happy for you to use as many editors as you want. We'd just like you to be working toward fluency in each.

Why is this a big deal? Are we saying you'll save lots of time? Actually yes: over the course of a year, you might actually gain an additional week if you make your editing just 4% more efficient and you edit for 20 hours a week.

But that's not the real benefit. No, the major gain is that by becoming fluent, you no longer have to think about the mechanics of editing. The distance between thinking something and having it appear in an editor buffer drop way down. Your thoughts will flow, and your programming will benefit. (If you've ever taught someone to drive, then you'll understand the difference between someone who has to think about every action they take and a more experienced driver who controls the car instinctively.)"
