Considering the following example of key binding in nvim init file:

vim.keymap.set(
  'n',
  '<leader>x',
  function()
    print('megatron')
  end )

Let's assume my leader is space ' '.

If I press x it works the first time. But I would like to continue to hold down (space), while I press again x, printing 'megatron' multiple times. Instead, starting from the second time, it begins to delete chars (as if I would have been pressed only x).

I would like to know if there is a way to map a function to holding space and press a char multiple times.
