Eclipse: convert upper case text to lower case and viceversa with a simple shortcut

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.

  • LOL, is not a difficult shortcut to remember :))

  • Thanks, exactly what I was looking for. :-)

  • Anyone know if there’s a shortcut key to convert to camel case ?

    As in, “SOME TEXT” too “Some Text”

    If these shortcuts are not working. You can find it in Menu Windows/Preferences/General/Keys
    Enter text “To Lower” to filter then assign shortcuts in Bindings field.
    Same for “Upper”.

    upper case to lowercase online.
