Are there any "common" text editors or word processors (Notepad, Wordpad, Word etc.) which allow you to invert the case of a string of text easily?
I've always thought there should be a shortcut so you can toggle the case between upper and lower, for example when you're...
sPEEDILY TYPING AWAY LIKE uSAIN bOLT
...but don't notice the dreaded CAPS LOCK is on.
I would rather convert it with a few clicks than type it out again as:
Speedily typing away like Usain Bolt
I keep meaning to write a macro or similar, but it never seems worth the effort at the time.
