* Notes on use:
*
* If no text is selected, the macro will operate on the current line.
*
* The caret position is part of the selected text; if the caret is at
* the beginning of a line, the macro will operate on that line.
*
* The use of HistoryTextField objects allows the macro to 'remember'
* past entries for the prefix and suffix.
