[Plugin: Page Menu Editor] What do I type to the fields?

Do I need to type in some kind of code in the text fields (Page Menu Label/Page Link Title Attribute)? Installation worked fine and the menu editor box appeared on the page editing views, but I can not get this to work so that menu text is short but the page headline is something else.
