I would like to have the keys M, J, K, L, U, I, O to be mapped to 0, 1, 2, 3, 4, 5, 6 (combine with the keys 7, 8, 9 already being on top of those keys) to be a total numpad when I hold a modifier key, say Alt/Meta.

In that way commands with numbers like 25j, d3w, etc. would be easier and faster to be typed. But I haven't figured out how to make this happen.

As it is said in this answer https://vi.stackexchange.com/a/2363/21584, I've tried this solution:

execute "set <M-j>=\ej"
nnoremap <M-j> 1

But it only works with commands which begin with a single number (7j), however complex commands which have number inside or multiple number (d3w, 25j) don't work.

I use Ubuntu 18.04, on terminal Kitty.

  • @klaus my bad, I mean Ubuntu 18.04. But I think that doesn't really matter.

  • copy-paste all the codes in your vimrc regarding this mapping, i.e. not just <M-j> but all of <M-k> etc. It would be easier for people to copy-paste themselves and as a result more easier to help you.

  • Creating mappings for this is potentially very hard—youd have to accept keypresses as long as it’s a « number » and then, when it’s not, feedkeys it all back to vim.

1 Answer 1


As I find out in this guide: https://howchoo.com/g/nzc1ztu4ztd/custom-key-mappings-vim#triggering-our-custom-key-mapping

What I was missing was the Operator-pending Mode, which is the case of the command like d3w.

This is how I modified the mappings (I didn't think it would turn out to be this simple):

noremap ^[j 1
noremap ^[k 2
noremap ^[l 3
" etc.

Where ^[ is the Escape character, and map applies the mapping for Normal, Visual and Operator-pending Mode. Now I can use Alt + J K L... to simulate the numpad on the right hand. Typing commands containing numbers is feeling more and more comfy now.

Hope this could help you guys :)

    Consider using :h :noremap version of :h mapmode-nvo

  • Thanks, it makes more sense to use noremap
