This is just a quick post to share these 2 little shortcuts to convert text from lower case to uppercase and viceversa in Eclipse.
Lower case: CTRL+SHIFT+Y (CMD+SHIFT+Y on Mac OS X)
Upper case: CTRL+SHIFT+X (CMD+SHIFT+X on Mac OS X)
In both the combination you can select one or more character to convert.
you can change this setting via Eclipse > Window > Preferences > General > Keys
