Vim: If editing line in window bottom, also show next 4-5 lines

Don't exactly know what to search for: If i edit text in vim it sometimes happen that i edit the last visible line. I'd like also to see the next 5 lines, so i'm looking for something like an "edit margin". Or something like: If i edit the third last line vim should scroll down 2 lines automatic. Wo开发者_如何学Gould this be possible?

Yes, you can do this using the scrolloff option.

:set scrolloff=5

This keeps 5 lines visible above/below the cursor.

You're looking for `set scrolloff=5'.
