Command implementation

The most direct approach to 1, 2 needs is to replace the whole text; for Demand 3, you can use block selection, then cut, paste! But not what Ben Boven to elaborate. Here's another way to implement this:

Requirement 1 command

:%s/\ (fan\) \ (jian\) \ (qiang\)/\3\2 \1/

Requirement 2 Command

:%s/\ (world\), change \ (mind\)/\2, change \1/

Requirement 3 Command

:%s/\ ([1-9][0-9]\)  \ ([1-9].\)/\2  \1/

This is how \ (\) is used

The pattern contained therein will be stored, numbered from left to right, with a maximum of 9 stored in one row. Access them by numbered access! For example, the above requirements 2,world saved to the number 1,mind to the number 2; so \2, change \1 the world and mind, changed the world, and replaced! Demand 1 and Demand 3 the same!

Description: Because \ and (combined into the escape of the Web page Italic font.) Instead of showing, here each \ and (between the spaces, note that the space is not part of the command
