The Workshop summarizes the key terms you learned and poses some questions about the topics presented in this chapter. It also provides you with a preview of what you will learn in the next hour.
colon commands The vicommands that begin with a colon, usually used for file manipulation.
escape sequence An unprintable sequence of characters that usually specifies that your terminal take a specific action, such as clearing the screen.
replace mode A mode of vi in which any characters you type replace those already in the file.
With this hour and the preceding one, you now know more about vi than the vast majority of people using UNIX today. There's a second popular editor, however, one that is modeless and offers its own interesting possibilities for working with files and the UNIX system. It's called emacs, and if you have it on your system, it's definitely worth a look. In the next hour, you learn about this editor and some of the basics of using it.
