Layout: Line Codes: Flush Right
Keystroke: ⇧F7
Flush right inserts a code to put the next word on the right margin. If you wish for more than one word to come under this command, you should put hard spaces between them, or group them.
If you want to set several lines flush right, you will want use the [ind] code with an optional third parameter, e.g. [ind0:0:r]. This is not available through a menu or shortcut, but can be entered directly using Control-[ to bring up a dialog allowing for direct code entry.
