Highlighting text and pressing Ctrl Caps Lock should make the text go to either lower or upper case depending on its original format. I have worked at many companies where you have to work with CAPS LOCK on in one program. It becomes annoying when switching back and forth from email to the program. I wind up typing a few sentences in CAPS LOCK and then stop and realize I need to rewrite those sentences in lower case otherwise it will look like I am yelling at the recipient. It would be great if a keyboard function solved this problem. I know it can be done in Microsoft Word but its ridiculous to open another program.
