Vim practical skills Reading Notes

Chapter 1

First, we put forward the idea of VIM: how to improve reuse -- easily repeat previous operations.
In addition, the author divides Vim operations into two steps:

One is mobile, and the other is operation.

For these two aspects, the reuse is achieved through commands: ";", "," n "," n ",". ", and" U.

1. Modify operation
   Command mode DD and so on are all modification operations, but it is easy to forget that: from entering the insert mode to pressing back to the command mode. This is also a modification operation.
2. Combined Command
   Vim combines some commands into a separate command to facilitate user operations. Of course, this also increases the burden on user memory. For example:
   A-> $
   S-> 0C $
   ....
3. "."
   "." Can be understood as the macro of the last modification operation recording.
