Menu: Edit > Swap Words
Default Shortcut Key: Shift+F4
Macro function: SwapWords()
The Swap Words command can be used to swap the word at the text cursor with the word to its right.
The characters which serve to delimit words can be set on the Configure | Preferences | Cursor Travel options page. The option is titled These characters will delimit words.
The last word on a line cannot be swapped, since the Swap Words command does not span lines.
