Greenfoot.getKey() with Shift

In GF 3.6.1 the getKey() method does not return any shift characters. Uppercase letters all appear as lowercase. Related, you cannot type and Shift-based characters like '?', '!', '@', '#', etc. getKey() returns "shift" when the shift key has been pressed and "control" for the control key. Is there a workaround or fix for this? act() { String input = Greenfoot.getKey(); if( input != null ) { System.out.println( input ); } }

Have you tried checking if both "Shift" and in case of "!" "1" are pressed by combining them with an AND operator?

This was what I was hoping, but getKey() consumes the key and only scans a single key. It seems to me that getKey() should return a KeyInfo object, like MouseInfo, that also stores key combos like SHIFT+ and CONTROL+ and ALT+. At least it should remove SHIFT and CONTROL from consuming the intended key press. I could try using isKeyDown("") but .... Most importantly, the documentation states that getKey() recognizes Uppercase: "getKey() also returns uppercase characters when appropriate." But even with the CAPS LOCK on, getKey() does not return uppercase letters. I'm left wondering what conditions "when appropriate" are applicable!
