vim: how to record and replay macros

To record a macro:

1. Start recording: press ‘q’
   
2. Choose a macro register: press ‘a’ to select ‘a’ as a location to save the macro to. You will see “recording” at the bottom left of the vim window.
   
3. Perform editing actions: for example, suppose you want to delete any line containing the string, “Stage:” You can do this by pressing:

   Esc
   /Stage:
   dd
   

   
   
4. Stop recording: press ‘q’

To replay a macro:

1. Choose a macro register: In our case, we want the macro we just saved to register ‘a’.
   
2. Repeat the saved macro: by pressing “@[register_name]” which in our case is:

   @a

   
   
3. Multiple-repeat: press “[count]@[register_name]”, for example:

   8@a
