In the defs, I've added a UFO formed from simple SVG arcs and circles, in order to avoid another huge block of path statements from the tablet.

现在有许多人固执的坚持他们不会用写字板和简单文本编辑器以外的软件编写他们的HTML。

You open what we call the "text editor," the specific one we used on Wednesday was called Nano, -- which is similar to Notepad or TextEdit -- totally simple, kind of dumbed down but in a useful way so that you can just focus on writing code and not learning some new interface.

你先打开那个“文本编辑器“,就是我们周三用过的叫做Nano的编辑器，这个跟写字板和记事本差不多-,非常简单的，只是通过一种有用的方法而进行精简了的,所以你们可以把注意力集中在编写代码上,而不需要学习一些新的界面操作。
