In the en_US locale, the following menu items should have ellipses ("...") after the text:
File | Open
Edit | Open Jrxml External Editor
Tools | Import Settings
Tools | Templates
Tools | Plugins
Tools | Options
...and most Help menu items.
Ellipses are typically used to indicate that choosing the menu item will open up another window or dialog for user interaction. The above menu items do open up dialogs, and therefore should have ellipses in their menu item text.
