Vim skills and pitfalls

The matching and replacement function of VIM is very fast and powerful, but it is hard to show the number of matches. It should be implemented around a bend:
The key to % S/xxx // gn is the final N, which indicates only the number of matched records is reported without actual replacement.

Vim v5 is powerful ..

 

In addition, if you are used to the editor on Windows, you need to change it. CTRL + S is the key. CTRL + s locked the shell.

It looks like your vim is so powerful. earlier on, if you thought it was a Vim error, press Ctrl + C to kill it and start over again. The feeling is sad.

In this case, use Ctrl + Q to unlock the shell lock.
