In some cases an IME may be able to display an arbitrary label for a command the user can perform, which you can specify here. This is typically used as the label for the action to use in-line as a replacement for the "enter" key (see EditorInfo.ActionId). Remember the key where this will be displayed is typically very small, and there are significant localization challenges to make this fit in all supported languages. Also you can not count absolutely on this being used, as some IMEs may ignore this.
