It's good to add the features

1.Add the keyboard shortcut mapping.
2. Set a keyboard shortcut to make it can switch every change-case case.
such as:
press ctrl + c: apply to camel command.
press ctrl + c again: apply to constant command.

Oracle's SQL Developer has a toggle case shortcut like this (Ctrl-') and it works great. It cycles through a number of common case types. You highlight a word, hold down control, and keep pressing the single quote key until it switches to the case you want. Fast and intuitive once you get used to it. Definitely a worthwhile feature to add.
