Support number mapping

[abiriadev]

The problem

In Vim, I used to map 8 and 9(which are too big numbers to repeat a single command in 99% of cases) to 10j and 10k, respectively, to quickly move the cursor.

What I tried

[keys.normal]
"8" = [
  "move_visual_line_down",
  "move_visual_line_down",
  "move_visual_line_down",
  "move_visual_line_down",
  "move_visual_line_down",
  "move_visual_line_down",
  "move_visual_line_down",
  "move_visual_line_down",
  "move_visual_line_down",
  "move_visual_line_down",
]
"9" = [
  "move_visual_line_up",
  "move_visual_line_up",
  "move_visual_line_up",
  "move_visual_line_up",
  "move_visual_line_up",
  "move_visual_line_up",
  "move_visual_line_up",
  "move_visual_line_up",
  "move_visual_line_up",
  "move_visual_line_up",
]

Expected result

It should work like Vim.
Or at least, it should show a warning message that it won't support number mapping.

Actual result

The editor starts without any error message, and the mappings are completely ignored.

Do you have any plans to support this feature? (I know this is not a common use case)

Regards.

Generally this seems really niche to me (why not just type 10j/10k) and don't really have an interest in this. If somebody implements a fix that does not regress any existing functionality and is small/easy to review and well implemented I wouldn't be opposed
