Question regarding more complex key bindings

[samuelbodin]

Following the template for more complex key bindings:

{
  "key": "YOUR_KEY_COMBINATION",
  "command": "vim.remap",
  "when": "inputFocus && vim.mode == 'VIM_MODE_YOU_WANT_TO_REBIND'",
  "args": {
    "after": ["YOUR_VIM_ACTION"]
  }
}

I am trying to map cmd+j and cmd+k to move cursor position 5 lines down/up

This does not work:

{ 
  "key": "cmd+j", 
  "command": "vim.remap",
  "when": "editorTextFocus && (vim.mode == 'Normal' || vim.mode == 'Visual')",
  "args": { 
     "after": ["5j"] 
   }
}

However, this does:

{ 
  "key": "cmd+j", 
  "command":  "vim.remap",
   "when": "editorTextFocus && (vim.mode == 'Normal' || vim.mode == 'Visual')",
   "args": { 
       "after":["j","j","j","j","j"]
    }
}

Is there any way I can specify the number of lines I want to go down without having to do as in the above example?
