Question

Answer 1

If you want to perform an action on a range of lines, and you know the line numbers, you can put the range on the command line. For instance, to delete lines 20 through 200 you can do:

:20,200d

To move lines 20 through 200 to where line 300 is you can use:

:20,200m300

And so on.
