Jenny says that if Richard uses normal tap mode only the characters he wants will appear, or show up, on the screen.

珍妮说，如果理查德使用正常的点击模式，只有他想要的字符才会出现在屏幕上。

It's that, like, you're all programmers, you like programming; Vim has this idea that Vim's normal mode, like, Vim's interface, itself, is a programming language.

就是说，你们都是程序员，你们喜欢编程； Vim 有这样的想法：Vim 的正常模式，就像 Vim 的界面一样，本身就是一种编程语言。
