Select Element Target for KeyEventViewer

[modellking]

Use case: We want to verify the KeyEvents on a select would select a valid option (it might not have loaded yet etc.) with a prefix match.

Adding the change Event would be awesome, too.

Also consider to allow editing the options, although this is not strictly necessary for a developer tool, because anyone who need specific options can manipulate the DOM in-browser nowadays, which is not possible for the select element itself, as it obviously holds the EventListeners
