What is Inverse Case?
Inverse case (also called Toggle Case or Inverted Case) inverts the case state of every individual character in a text block. If a character is uppercase, it is flipped to lowercase; if a character is lowercase, it is flipped to uppercase.
Input: hELLO wORLD! tHIS IS cASEcRAFT.

The Caps Lock Mistake Fixer
The most common practical application of Inverse Case is fixing text typed when the Caps Lock key was accidentally left on with the Shift key pressed for first letters. Inverse Case reverses the error in a single click without retyping.
