DON'T YOU GET ANNOYED WHEN YOU ACCIDENTALLY TYPE EVERYTHING WITH CAPS LOCK ON? Wouldn't it be awesome if you could just select the text and press Caps Lock again to reverse the mistake instead of typing it all over again? SmartCapsLock lets you do just this.
Or do you wonder why that key sits in your keyboard even though it serves no purpose for you? SmartCapsLock finally gives a use to the key and makes it very convenient when you need to quickly transform any text to a different case (UPPER CASE, lower case, Capitalized Case).
