The steps for recording and running a macro in Vim are:
While in normal mode, start with your cursor at the beginning point of where you want the recording to start. Then type q followed by the letter you want to define as the register, such as a After pressing q + the register, perform all of the tasks that you want to record, if you're performing a task such as changing each line in a file, make sure you finish on the next line. Press q to finish the macro recording Press the number of times you want to execute the macro, such as 500, followed by @ follwed by the register key, so an example would be 500@a - which will run the macro 500 times.If you discover that your macro didn't work properly, typing u to undo will undo all of the changes and allow you to record the macro again with the fix.
