end of a word, and moves to the fist letter of next word for n times.
The description of the command may seem a little bit cryptic. What is really happening is that there are situations where you want to upper case only the last part of a word. In this case, you just have to position the cursor in the first character you want to upper case, and use this command with no argument.
If you apply
ToUpper on the first character of a word, it will
just upper case n words.
