2. Move to the end line, and enter Y ' A to copy the text between the current line and the mark A. d ' A will be deleted.

or V into the visual mode, then 13G jump to the corresponding line, Y can.

: 10,20y Enter, the corresponding deletion is also true: 10,20d (this method is simpler than the two methods above)

If you want to type a phrase or a sentence repeatedly, there is a quick way. Vim has a mechanism for recording macros. You type "QA" to start recording a macro into the register variable ' a '.
Press down you can type the action you want as usual, but these actions will be recorded by Vim in the macro named ' a ', and then the "Q" Key again to end the macro ' a ' recording. When you want to repeat the actions you just recorded, just use the "@a" command. A total of 26 registers are available for you to record macros. With macros, you can repeat several different actions. Instead of just inserting text. If you want to do something repetitive, remember to use this trick.
