Add characters to the press and hold character picker in OS X Lion
I’m slightly disappointed by Lion’s iOS inspired feature to show a selection of accented characters on key hold.
On a German keyboard, when pressing a, I am able to choose between
ā. So far so nice.
However, I feel some characters are missing. There is no
ç (although I could type this one using option+c), no
ğ and no
ł either. On the other hand the letter
ń is shown (which like
ł is more or less only used in Polish) but to which OS X does not show an upper case version. shift+n yields no results.
Is there some way to enhance and expand this set of letters with own additions?
