>> This PR adds code to ensure that KeyCodeCombinations match KeyEvents as expected by more accurately mapping from a Mac key code to a Java key code based on the user’s active keyboard layout (the existing code assumes a US QWERTY layout). The new code first identifies a set of Mac keys which can produce different characters based on the user’s keyboard layout. A Mac key code outside that area is processed exactly as before. For a key inside the layout-sensitive area the code calls UCKeyTranslate to translate the key to an unshifted ASCII character based on the active keyboard and uses that to determine the Java key code.

If it lies in the layout-sensitive area the code then scans the entire area calling UCKeyTranslate until it finds a match. If the key lies outside the layout-sensitive area it’s processed exactly as before.

thank you for making changes for eclipse!

LGTM, but I hope we could get more neocortexes to look at this PR.
