A DESCRIPTION OF THE PROBLEM :
If you make a KeyCodeCombination that includes KeyCode.BACK_SPACE, the getDisplayText for that will return "Back Space" instead of "Backspace"

Looking at the implementation of getDisplayText, it seems to be calling KeyCode.toString, which returns the source-code name of the Enum, and then does some processing to get the correct case on the words. This seems like it could be replaced with a call to the getName() method on KeyCode, which returns a nice human-readable representation of the key

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached source on Windows

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The sample program should print "Ctrl+Backpace"
ACTUAL -
The sample program prints "Ctrl+Back Space"
