[mod] improve handling of the hotkeys

- KeyboardEvent: keyCode property is depricated, replaced by key property [2]

- the check for ifDetailOpened is not necessary, because the hotkeys are not
  only applicable to image-results, by example:

   `!goi !go !scc hello`

- Key bindings like h for help are to be used in general (not only in vim-mode)
