That's what I mean by fiddly. A little unobtrusive half-size umlaut key for those occasions would be the thing. I've got a pause/break key - never use that, or the scrl/lck, or the mail button, or the web home button. Lot of junk on keyboards could be replaced by an umlaut. I bet the Germans have special umlaut keys. I bet even the Austrians have them eh ?
