On my iMac, when one pushes certain character keys after about 1 second a menu appears with the selected character with diacritic marks (accents) - i.e. when one presses S, one is presented with a menu showing ß ś š. You can then choose to insert one of these characters using the numerical keys (i.e. pressing S ... short wait ... press 1 results in a ß).
(I'm not sure if this is the default macOS behaviour, or a setting for my Mac. The keyboard in System Preferences implies that holding a key should repeat that key because it has "Key Repeat" and "Delay Until Repeat" settings.)
Is it possible to decrease this wait time? I've been typing in German a lot recently, and ending up with a4 in my text when I intend to write ä.
