Case Toggle Tool
Invert the case of text, turning every uppercase letter lowercase and vice versa.
Flipping the case around
Case toggling swaps each letter to its opposite — capitals become lowercase, lowercase becomes capitals. Its most useful moment is rescuing text typed with Caps Lock on by accident, where your careful capitals have all landed wrong: what should be This is a Test came out tHIS IS A tEST, and a single toggle sets it right.
Paste the text and every letter's case is flipped.
Toggle versus the other case tools
It is a specific operation, not the same as the general case converter. Converting sets text to a chosen case — all upper, all lower, title. Toggling inverts whatever is already there, letter by letter, which is exactly what you need for the Caps-Lock-reversed situation and little else. Knowing the difference means you reach for toggle for that one job and the converter for everything else.
