ECLIPSE Shortcut for converting lower case to upper and vice versa

Just a quick short cut which is very useful for developers to convert the selected lower case text to Upper case and vice versa

Lower case: CTRL+SHIFT+Y (CMD+SHIFT+Y on Mac OS X)
Upper case: CTRL+SHIFT+X (CMD+SHIFT+X on Mac OS X)

The good thing here is you can select one or multiple characters/word/lines by using Using + ->/<-/DownArray and then convert all of it at once.
