ParagraphSortAllKeyEntireAscending

Under.zip (XSort) " ParagraphSortAllKeyEntireAscending " - Sort paragraphs of a selection in ascending sequence.
Open a new document and Insert a File from another document (a safer method of obtaining text than opening a precious file!). Choose (Under) Sort, Paragraphs, ParagraphSortAllKeyEntireAscending and note how the document is sorted by paragraphs.

If you select a block of paragraphs, that selected block will be sorted while the remainder of the document is unchanged.

If the selection is the text insertion point (as in "Ctrl-Home"), then the entire document will be sorted.
