Problem with getKey()

My code below only works with space, enter, control and so on. Why isn't working with a normal letter like k?
if (Greenfoot.getKey() == "k")
     {
         if (automove == false)automove = true;
         else automove = false;
     }
     if (automove == true)
     {
        showText("test", 200, 200);
     }
     if (automove == false)
     {
        showText(" ", 200, 200);
     }

you can use isKeyDown : 
if (Greenfoot.isKeyDown("k"))
{
    //do stuff
}

But then this triggers every act and it's working perfectly fine with enter. Is there a way to use getKey with a normal letter?

hmm, I really don't know sorry, I never tried getKey(), did you try putting "k" in capital letter : "K" ?

I did it with isKeyDown but yes I tried different things but nothing worked.

You can try this: 
String key = Greenfoot.getKey();
if ("k".equals(key))
{
    automove = !automove;
    showText(automove ? "test" : " ", 200, 200);
}
else if ("enter".equals(key))
{
    //...
}
Generally, the “getKey” method is a good option for text input, but not so much for gameplay mechanics. General advise: Make sure to never call the “getKey” method more than once per act cycle because it will only work once.

Your solution also only works with enter

try to test something : write something like this : 
if(Greenfoot.getKey() != null)
    System.out.println(Greenfoot.getKey())
and then press the "k" key to see what it prints

I already tried that and it gave out k so I really don't know how this doesn't work.

Is your Caps-Lock on?

Try: 
System.out.println(""+automove);
to verify getting both true and false.

Maybe your k key is broken? The code works on my side.

Hippo's suggestion/code is best. Gbasire's last post breaks the "General advice" given by Hippo.

Try a different key, like "a" (for automove).
