vim - how to bind the screen scroll down command

Question

I try to press ctrl-d to scroll half-page down. However, it springs a nerdtree table. Now I try to map ctrl-d to the origin command, after trying :scroll, :startofline... I can't figure out how to bind the origin command.

Answer 1

You can use :unmap <C-d> to remove the mapping.

Use :verbose map <C-d> to see what it's mapped to and where it was last mapped.
