Change doc tapping D to V

[mingrui]

Hi, nice work!

just a minor change to official docs would be great for newbies, change D tapping + navigation to V, because:

1. V is a much less used letter, so in normal typing you rarely have to tap V, in English:

2. V key stays in the same location across different key maps:
   QWERTY and Colmak, V stays at the same place

3. The strongest finger is your index finger, more ergonomic to use this finger to press and hold a key

: D

Also this would lead to one big issue.
Most games use WASD to move around.
so when you are holding down d you expect your game character to move to the right.

This will lead to massive confusion for first time users.

I personally use caps lock a backspace when pressed
and when hold activates a layer with arrow keys under the wasd keys.

The main reason to use D as a Tap-key is to keep our fingers at the home row. We want to highlight the idea.
It is configurable. Both V and Capslock are appropriate alternatives. It's hard to choose one.
People like you who are interested in this keyboard is likely to customize the keyboard.
