arrow_right should open text file in nvim (if only one command is in a text_default list)

[srghma]

I have

mimetipes.yaml (I commented out all commands except of one )

text_default = [
  { command = "nvim" },
  # { command = "micro" },
  # { command = "gedit", fork = true, silent = true },
  # { command = "bat", args = [
  #   "--paging=always",
  # ] },
]

joshuto.yaml (default)

  { keys = ["arrow_right"], commands = ["open"] },
  { keys = ["\n"], commands = ["open"] },

Actual: I click [left] button -> in opens command line with :open_with text -> I have to write :open_with nvim - I click [enter] button -> opens nvim program
Expected: I click [left] button -> opens nvim program (bc it is the only one command in a list)
