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. There are 26 registers available for you to record macros. You can repeat several different actions by using a macro. Instead of just inserting text. If you want to do something repetitive, remember to use this trick.
